Introduction
With every passing year, more red dot sights are available on the market. There have never been as many optics manufacturers as there are now, which means that there have never been as many different optical devices as there are now.

Terminology
When this article was first written, there was some inconsistency in the use of terminology. This is why we decided to dedicate this paragraph to explaining the differences between the terms screw hole pattern, bolt pattern, socket pattern, mounting standard, and footprint.
Screw hole pattern
The screw hole pattern refers to the screw hole (bolt) position on a red dot sight.
Bolt pattern
This is just another term used to refer to the screw hole pattern.
Socket pattern
The socket pattern refers to the dimensions and distances between the sockets on the red dot sight’s mounting surface.
Mounting standard
The screw hole pattern (bolt pattern) and the socket pattern form a mounting standard. Red dot sights that share a mounting standard can be mounted on the same adapter.
With Aimpoint Acro, Holosun 509T, and some other standards, there are neither screw holes nor any sockets on the mounting surface. When using the term ‘mounting standard’ to talk about these sights, we refer to the dimensions of the clamping mechanism on the red dot sight’s mounting surface.
Footprint
The term footprint encompasses the mounting standard and the entire bottom surface of the red dot sight. To give you a better understanding, if the mounting surface was pressed into the sand, the three-dimensional imprint would show (match) the footprint of the device.
Differentiating between these terms is important, especially if you have a custom pistol slide cut. In that case, you want the red dot sight to sit in the cutout perfectly, so taking only the mounting standard into account is not enough; you want a red dot sight whose footprint matches the cutout perfectly.
In this article, the most common mounting standards used on red dot sights are listed. Each standard is described and an image of it is added. Within each mounting standard section, the red dot sights that share it are enumerated. Next to each sight, there is a link to the dimensions of its footprint (we will gradually be adding these).
Docter/Noblex mounting standard
This is one of the most widely used mounting standards in the field of red dot sights. It has two holes for screws and four sockets in which the pins on the mount/adapter fit, one in each corner. There is a wide range of mounts for this mounting standard on the market, which is one of the main reasons why it is used by so many manufacturers. Docter/Noblex standard is simple and reliable.
Red dot sights that share this mounting standard:
* These red dot sights have a Docter/Noblex mounting standard, but the adapter supplied with them has wider threaded sockets than adapters suited for a Docter/Noblex mounting standard. Consequently, thicker screws are enclosed. You can mount these red dots on an adapter designed specifically for the Docter/Noblex mounting standard, but you will not be able to use the screws supplied with them – thinner screws are needed.
**The screw holes do not accept a 6-32 screw.
Note: distances between holes (sockets) are measured from and to the center of the hole (socket).
Modifications of the Docter/Noblex mounting standard
The following red dot sights come with a mounting surface that is very similar to the one used by Docter:
| Red Dot | Product | Details |
|---|---|---|
| Bushnell AR Optics Micro Reflex | ||
| Meopta Meosight III | ||
| Delta Optical MiniDot HD 25 | ||
| Meprolight MicroRDS |
The four sockets, one in each corner, are in the exact same places. The holes for the screws, however, are not. This is why Meopta Meosight III, Delta Optical MiniDot HD 25, and Meprolight MicroRDS cannot be mounted on every adapter designed for the Docter/Noblex mounting standard. Several adapters are designed so that red dot sights with a Docter/Noblex mounting standard and Meopta Meosight III/Delta Optical MiniDot HD 25/Meprolight MicroRDS can be mounted on them (see the images below).
Aimpoint Micro mounting standard
Aimpoint is the first company to have used this mounting standard on their Micro small tube sights. Today, other manufacturers of this type of sights use it as well. The surface of the mounting surface is slightly lifted in the middle – on each side of the lifted section, there are two holes for screws. The lifted section is cut in the middle – this is where the recoil stop fits.
Red dot sights that share this mounting standard:
Modifications of the Aimpoint Micro mounting standard
Red dot sights that feature a modified Aimpoint Micro mounting standard:
- GPO Spectra
- Hawke Endurance 1×25
- Hawke Endurance 1×30
- Rudolph Optics 1×20
- Vector Optics Maverick-IV 1×20 Mini
- ADE Advanced Optics RD4-005
GPO Spectra uses a mounting surface that is identical to the one used by Aimpoint Micro. Even though it appears to be the same at first sight, there is a protruding part underneath the illumination knob. Because of it, the adapters designed for the Aimpoint Micro mounting standard do not fit into place at that side (check the picture below). GPO Spectra uses a unique adapter with narrow side sections.
Hawke Endurance 1×25 and 1×30 red dot sights also use a mounting surface slightly different from the Aimpoint Micro one. The lifted section in the middle is wider, thus adapters designed for the Aimpoint Micro mounting surface do not fit in place.
This red dot sight features a modified Aimpoint Micro mounting standard – the recoil notch in the middle of its footprint is missing. Nearly all mounts designed for the Aimpoint Micro mounting standard come with a recoil stopper in the middle, which is why it is nearly impossible to find an aftermarket adapter made by a renowned mounts manufacturer for Rudolph Optics 1×20.
Vector Optics Maverick-IV 1×20 Mini
This red dot sight features a modified Aimpoint Micro mounting standard. The distance between the two screw holes on each side of the recoil stopper is 8.8 mm instead of 10 mm. Because of this, Vector Optics Maverick IV 1×20 Mini is not compatible with adapters designed for the Aimpoint Micro mounting standard.
This red dot has a modified Aimpoint Micro mounting standard. The recoil notch in the middle of its mounting standard is narrower, measuring the same as a Weaver recoil notch, 3.8 mm. Furthermore, the distance between the screw holes in the front and in the rear is 2 millimeters bigger than on Aimpoint Micro mounting standard.
C-more RTS/STS mounting standard
This is a mounting standard found on C-more’s popular red dot sights, RTS and STS. Some other manufacturers also use it because of its simplicity and reliability. The standard consists of two holes for screws and two sockets in which the pins on the mount/adapter fit.
Red dot sights that share this mounting standard:
Shield RMS/SMS mounting standard
Shield sights are incredibly compact, which is why Shield had to come up with a mounting standard of their own. It is designed similarly to the Noblex/Docter mounting standard (there are two holes for the screws and four sockets in which the notches on the mount/adapter fit, one in each corner). The sockets, however, are a little bit wider and closer one to another.
Red dot sights that share this mounting standard:
Important notes
Even though Shield RMS and RMSc differ in dimensions (the ‘c’ version is smaller), the distances between the holes are the same, which is why an adapter designed for the Shield mounting standard fits on both.
- RMSc -(length x width x height) 40 x 23 x 22 mm
- MS – (length x width x height) 42 x 25 x 23 mm
Modifications of the Shield RMS/SMS mounting standard
Leupold DeltaPoint Pro mounting standard
Even though Leupold DeltaPoint Pro fits on mounts designed for the Shield RMS/SMS mounting standard, it does not result in a secure fit, because its sockets are wider than the pins on adapters for Shield RMS/SMS. Therefore, mount manufacturers usually produce mounts specifically for the Leupold DeltaPoint Pro. Furthermore, red dot sights with the Shield RMS/SMS mounting standard do not fit on mounts designed specifically for the Leupold DeltaPoint Pro.
The four sockets on Leupold DeltaPoint Pro’s mounting surface are wider than those on a Shield RMS/SMS mounting standard. Namely, the sockets measure 4.2 mm in diameter, while the sockets the Shield RMS/SMS mounting standard measure 3.8 mm in diameter.
Red dot sights that feature this mounting standard:
| Red Dot | Product | Details |
|---|---|---|
| Holosun SCS 320 | ||
| Leupold DeltaPoint Pro |
Holosun 407/507K mounting standard
The differences are:
- the two rear sockets are missing (see the photo below)
- the sockets in the front are shallower (see the photo below)
For this reason, some pistols that are optic-ready for the Shield mounting standard need to be modified for the 407 and 507K. Namely, the two rear indexing lugs on the pistol have to be removed and the two front indexing lugs shortened in height. Hellcat and Walther PPS are examples of such pistols (some pistols, such as Sig Sauer P365XL, do not have to be modified).
| Red Dot | Product | Details |

| Holosun 407K | Discontinued | |
| Holosun 507K | Discontinued | |
| Holosun 407K X2 | ||
| Holosun 507K X2 |
Holosun EPS mounting standard
The red dot sights listed below feature a mounting surface modified even more extensively (compared to the Holosun 407/507K modification):
The mounting surfaces of these red dot sights have the same modifications as those found on Holosun 407/507K devices, with an addition of the following features:
- There are two additional sockets in the front part of the mounting surface, placed in between the usual ones. Holosun produces plates that convert this specific mounting surface to the other ones (Trijicon RMR, for example).
Trijicon RMR mounting standard
This mounting standard consists of two holes for screws and two sockets in which the pins on the mount/adapter fit – these are in the front, in each corner. Even though the sockets are in the front only, the mounting standard is somewhat reminiscent of the Docter/Noblex one. Note, however, that the sockets in the corners are farther apart on the Trijicon mounting standard and bigger in diameter.
Red dot sights that share this mounting standard:
Modifications of the Trijicon RMR mounting standard
Red dot sights that feature a modified Trijicon RMR mounting standard:
This red dot sight has two additional sockets on its mounting surface. They are located in each of the rear corners. Furthermore, the sockets are 0,1 mm narrower and the screw holes are 0,4 mm wider than on the standard RMR mounting standard. Nevertheless, mounts designed for the Trijicon RMR mounting standard can be mounted on ADE Advanced Optics RD3-019 Stingray.
Trijicon MRO mounting standard
This mounting standard comprises four screw holes, two in the front, two in the rear. The holes on the left are separated from the holes on the right with a lifted section in the middle.
Red dot sights that share this mounting standard:
| Red Dot | Product | Details |
|---|---|---|
| Trijicon MRO | ||
| Trijicon MRO Patrol | ||
| Burris RT-1X |
Important notes (Burris RT-1X)
Burris RT-1X’s mounting standard is the same as the one on Trijicon MRO, but there is a difference in the supplied screws. RT-1X comes with screws that have bigger heads than the ones supplied with the MRO, which is why you cannot use them to fix an original Trijicon adapter on the Burris red dot. If you wish to mount an original Trijicon adapter on the Burris RT-1X, you have to use the screws supplied with the Trijicon adapter (see the picture below).
Modifications of the Trijicon MRO mounting standard
Vector Optics Centurion 1×30 features a modification of the Trijicon MRO mounting standard. The distances between the screw holes are the same, and so is the thread. The difference is in the lifted section. On Centurion, the middle part of the lifted section is cut out to create space for a recoil stop. For this reason, a mount designed for the Trijicon MRO mounting standard fits on the Centurion, while a mount designed for the Vector Optics Centurion (with a recoil stop) does not fit on the MRO (the middle part of the lifted section is not cut out).
Glock MOS mounting standard
Glock devised the MOS system in 2015. MOS stands for Modular Optic System. This was one of the first optic-ready sistems introduced on a pistol, and the standard has been gaining in popularity ever since. There are two screw holes between the front and the middle part of the mounting surface. Usually, a plate is used to convert the MOS standard to any other ones, but some red dot sights are designed to fit directly on it.
Red dot sights that share this mounting standard:
| Red Dot | Product | Details |
|---|---|---|
| Holosun SCS MOS | ||
| Noblex Red Dot Sight for Glock MOS |
Walther PDP 2.0 mounting standard
Walther’s PDP models are optic-ready, but there is a difference between the cuts of 1.0 and 2.0 models, so you have to be careful if you are looking for a mounting plate. Red dot sights with this mounting standard are designed to fit directly on the Walther PDP 2.0 models, no additional plates are required. There are two screw holes for mounting purposes. See the image below for more details.
Red dots that share this mounting standard:
Heckler & Koch VP9 mounting standard
This mounting standard is compatible with Heckler & Koch VP9 optic-ready pistols. Red dot sights equipped with it fit directly on the pistol cut, no additional plates are required. There are two screw holes for mounting purposes – check the other characteristics of the standard in the image below.
Red dots that share this mounting standard:
Holosun SCS VP9 Footprint, featuring the Heckler & Koch VP9 mounting standard
Smith & Wesson M&P 2.0 mounting standard
This mounting standard is designed to fit directly onto the cut of Smith & Wesson M&P 2.0 optic-ready pistols, without having to use an additional plate. There are two screw holes for mounting purposes – the other features can be observed in the image below.
Red dots that share this mounting standard:
Aimpoint Acro mounting standard
Aimpoint designed a new mounting standard for their Acro red dot sights. There are grooves on the side of it with a movable part used to fix the red dot sight in place. The movable part is connected to a recoil stopper. The system is similar (but not the same) as the one designed for a Picatinny rail.
Red dot sights that share this mounting standard:
| Red Dot | Product | Details |
|---|---|---|
| Acro C-1 | ||
| Acro C-2 | ||
| Acro P-1 | ||
| Acro P-2 | ||
| Steiner MPS | ||
| Vector Optics Frenzy Plus 1x18x20 |
Note: distances between holes (sockets) are measured from and to the center of the hole (socket).
Steiner MPS features the same mounting standard as Aimpoint ACRO but its footprint is slightly different. The grooves in which the adapter fits are not in the exact same place but the recoil notch is. This is why adapters designed for Aimpoint Acro can be mounted on MPS as well. The same applies to Vector Optics Frenzy Plus 1x18x20.
Aimpoint CompM4 mounting standard
The screw holes, one on each side of the mounting standard, are located on the lifted sections which work as recoil stoppers when fixed on an adapter. The same applies to the lifted section in the middle.
Red dot sights that share this mounting standard:
| Red Dot | Product | Details |
|---|---|---|
| Aimpoint CompM4h | ||
| Aimpoint CompM4s |
C-More Railway mounting standard
This is one of the longest mounting surfaces available in red dot sights. There are two screw holes on it for mounting purposes. The mounting surface is flat.
Red dot sights that share this mounting standard:
| Red Dot | Product | Details |
|---|---|---|
| C-More Railway | ||
| C-More Tactical Railway | ||
| C-More Slide Ride |
Modification of the C-more Railway mounting standard
The following red dot sight uses the same form factor but the mounting solution is completely different.
The dot is attached to the pistol by means of drilling and tapping the frame via the integral polymer mount.
C-MORE SERENDIPITY INSTALLATION
The Serendipity was originally designed to attach to 1911 style handguns for competition shooting by drilling and tapping the frame and mounting the sight directly via the integral mount.
The mounting legs allow for a maximum slide width of .950″ (A).
The mounting legs allow for a maximum slide height of 1″ (B).
The mounting pads can be machined to accomodate frame widths between .750″ and 1″ (C).
Holosun AEMS mounting standard
Holosun introduced this mounting standard in 2022 on AEMS and AEMS Core models. There are two sockets in the front part, a screw hole next to each of these sockets, and two more screw holes close to the central part of the surface. There is a recoil stop between the screw holes.
| Red Dot | Product | Details |
| Holosun AEMS | ||
| Holosun AEMS Core |
Red dot sights that have a unique mounting standard
Trijicon RMRcc has a mounting surface without recoil-stopping sockets. There are two holes for screws between the middle and rear section. The size of the mounting standard is similar to Shield RMS/SMS, Leupold Delta Point Pro, Holosun 407/507K, etc.
This red dot sight has a unique mounting surface that works similarly to the mounting standard designed for the Picatinny rail. The adapters suitable for it are slid into place and then fixed with the movable side section. A recoil stop helps keep the adapter in place.
The mounting surface of the Infinity models is flat, with three notches for recoil stoppers. The adapter is fixed in place with four screws.
Sig Sauer’s Romeo 1 1×30 has a mounting standard suitable for mounting on certain Sig Sauer pistols – you will need a special adapter if you wish to mount it elsewhere.
- Steiner MRS
- Steiner MRS Universal
All Steiner MRS red dot sights share the same mounting standard – there are only two narrow notches in the front, while the holes for the screws are located at the rear of the sight, on both sides, left and right.
The ‘Universal’ model, however, is supplied with an adapter that converts the mounting standard into the one designed for Docter/Noblex adapters.
- Holosun Paralow 403A
Holosun 510C has 10 screw holes on its mounting surface, 6 in the front and 4 in the rear. There are two lifted sections in the middle which work as recoil stoppers.
Even though the mounting standard found on Vector Optics Nautilus 1×30 looks identical to the one on DI Optical RV2, there are minimal differences between the two. The lifted sections with screw holes are narrower on RV2. Because of some other minimal deviations, the supplied adapters are not interchangeable between these two sights.
The mounting standard on Sightmark Volta is somewhat similar to the Aimpoint Micro mounting standard, but the distance between the front and rear holes is bigger. Furthermore, the recoil notch is wider.
The mounting standard on Vector Optics Wraith 1x22x33 is an enlarged version of the Docter/Noblex mounting standard. There is a socket in each of the four corners and two screw holes in the rear part of the surface.
This mounting standard is similar to the one on Vector Optics Wraith, but the distances between the sockets and the screw holes are not exactly the same. There are four sockets, one in each corner, and two screw holes in the rear part of the surface for mounting purposes.

Adapter plates
An adapter plate is needed if you wish to mount a red dot sight on your handgun. As there are red dot sights with different mounting standards on the market, it is important to pick the suitable one. Some handguns are optic-ready and come with a mounting standard-specific plate. In the following link, you will find a vast selection of red dot sight plates that either fit directly on a specific handgun or convert the existing mounting standard to make it compatible with another mounting standard:
Optic ready handguns
The popularity of optic ready handguns is on the rise. Do you have an optic ready handgun and wish to know how to mount a red dot sight on it? We are working on making it simpler for you. Below is a list of all the optic-ready handguns we have examined so far.

If you have a compact reflex or small tube sight that isn’t listed in this article, please be so kind as to send a picture of the sight and its footprint to [email protected] – help us expand our database. We greatly appreciate everyone’s help!
This article is regularly updated with new information and user contributions. We aim to create a collection of useful data that will be of great help to users, potential buyers of red dot sights, and those who are looking for a specific mount/adapter for their red dot sight.
Do you have plans on adding the Eotech ELFX?
From EoTech, the EFLX will use the Leupold Delta Point Pro footprint.
Unfortunately, I haven’t been able to acquire Eotech red dot sights yet, but I will add them as soon as I do.
Bushnell Optics First Strike 2.0 is not listed on your sight. Please update.
Unfortunately, I haven’t had an opportunity to get one of those yet. Do you have any information on its footprint?
I am looking for info. Company does not give that info out!
Hi! I don’t see Glock MOS mentioned at all? I can’t find accurate cutout dimensions anywhere. Holosun came out with the SCS pistol green dot sight recently, but it is only is available for Glock MOS mounting. I don’t see anyone sells an aftermarket Glock Gen 3 slide with MOS cut, they are all RMR cut. Gen 4 and Gen 5 slides don’t fit the Gen 3. It would be nice to see what the standardized MOS dimensions should be before I machine my slide.
Aaron, thank you for bringing up the MOS footprint. It is definitely on my bucket list. I haven’t been able to get hold of any MOS red dot sights yet, but I am expecting to receive the SCS in the near future. When I do, I will add it to the article!
I called Glock customer service today, and I asked for their MOS system mounting dimensions. They said “we do not provide that”. I said ok, so how do I be sure an aftermarket MOS sight is the correct dimensions for a Glock MOS slide? I also said, it’s not like it’s some proprietary information, it’s intended to work with other company’s sights, I just want the proper measurements. They said “no, we do not provide that information”. And he added “if you modify your slide it will void your warranty”. Really? Its that pretty obvious? Now its like a personal challenge, that is ridiculous. I will make my own accurate measurements and post them for the public, this should be readily available.
I’ve heard several times about manufacturers unwilling to give information on certain footprints, and I don’t quite understand why they are so secretive about it. I will also do my best to post MOS measurements as soon as possible …
I had this same problem with Springfield Armory and wrote to someone higher in the foodchain in the company and THEY got me the information I needed. I asked them how was I supposed to put a red dot sight on the pistol if they wouldn’t give me the information, and could they please ask the people who DESIGNED IT to pass along the specifications?
That actually worked.
I think the people doing tier one support in customer service at most of these companies are just clueless folks who really have no idea what they’re doing. You have to get past them to someone higher up.
Do Aimpoint Pro Mounting system and Aimpoint Acro red dot sight mounting hardware are same? Because I have Aimpoint Pro and now I want to buy Acro red dot sight. Please let me know if anyone of you has any experience.
No, Aimpoint Pro is mounted with a 30mm ring, whereas the Acro has its own mounting standard. Here are the dimensions of the footprint of ACRO C-2:

Good evening ANDRAŽ.
I just recently purchased a Walther PDP. I was told at the gun shop that Walther will provide a slide for the red dot. Now I cant find a slide that fits the SIG Sauer Romeo 1 Reflex.
Can you help me out?
Thanks
I am sorry, Christopher, unfortunately, I do not know of such slides. Sig Sauer Romeo 1 has a very specific, unique mounting standard.
This is an awesome article. It is very helpful will the multitude of mounting options out there.
With that being said, will there be an update to address the Trijicon RMRcc standard and which red dots will fit that footprint?
Thank you for your kind words!
Yes, as soon as I come across a red dot sight that shares the mounting standard with RMRcc, I will add it to the category.
Yes I understand the RMRcc is still very new.
What I’m looking for specifically is a red dot for my Canik Mete SFX. Canik states it can mount RMRcc or Shield SMS/RMS footprints. I was looking at Holosun 507k x2 but it says its a modified RMS footprint. Will it still fit the Canik Mete SFX?
Also, I’m not real familiar with Swampfox Optics. How are they comparative to Holosun?
This article may be updated constantly, but with very little useful information.
If I wanted a list of just green dot sights – where would I find that? Not here.
Information that is useless to you might be useful to someone else. Many green dots share the footprints of their red counterparts. Which green dot do you have in mind?
Sorry, a lot of the information you have on here is useful. I am just frustrated at the dearth of useful info in database-type formats.
What I am looking for EXACTLY is a green dot sight, less than one inch wide, for a pistol. In my mind I should be able to simply look at all of the dot sights available, select “green reticle” and “width less than an inch” as narrowing criteria, and get a list of results.
As it stands, no one has anything like this, so I am stuck. I can’t even find a website that lets me narrow down dot sights to green-only reticles. It is extremely frustrating.
What this site tells you, is what the footprints look like, and how they compare. Which is a lot more important that what you’re looking for, as nobody else in the world has this information. Which leads me to THIS question:
What sight does your pistol have a mount machined into the slide for? If your pistol Doesn’t Have a Mount, then who are you going to send it to, to have a mount machined into it?
Before you even start looking for a sight, you have answer that question. You can not just slap a sight onto any pistol. They have to be machined for it first.
As for small, I have the swampfox sentinel : https://www.swampfoxoptics.com/ it comes in Red and Green and I’ve been happy with it.
Actually, I CAN “just slap a sight onto any pistol,” because I have a shop that will do exactly that – machine whatever pistol I have to accept any RDS/GDS I choose. So, for me the footprint is unimportant. What is important – to me – is seeing everything that is available so I can be sure I am making a decision with all of the possibilities in hand.
I have seen the Swampfox offerings and they are intriguing – I have not ruled them out of anything at the moment.
Yes, most online stores do not have filtering options that include dimensions. The only green dot sight that comes to my mind is Holosun 507K-GR X2 which shares the dimensions of its red counterpart:
https://www.optics-trade.eu/blog/holosun-507k-x2-footprint/
https://www.optics-trade.eu/en/holosun-507k-x2.html
Sadly, only a handful of manufacturers produce green dot sights, and there are only a few compact green dot sights out there.
Hello,
I am newer to the optics mounted red dots, having only 2 at this time, both of which had lugs that went into corresponding holes in the site to help secure the optic. I recently purchased a B&T mkII which has the Shield RMS footprint and am looking for an optic to direct mount to the slide. The only version I could find at LGS had no lugs at all and would only secure by the two screws. What am I missing, shouldn’t at least two lugs be used plus the screws? Any help would be appreciated
Were you looking at Trijicon RMRcc? This red dot lacks mounting sockets, it only comes with two screw holes:
https://www.optics-trade.eu/blog/trijicon-rmrcc-footprint/
It is not compatible with the Shield mounting standard.
I suggest that you check the list on the following link and find the dot with the dimensions that suit your B&T’s slide.
https://optics-info.com/footprints-on-red-dot-sights/#shieldstandard
Not exactly. I have a Riton MPRD with a Shield Footprint but no lugs are protruding from either the slide or the sight. Both the sight and slide have recesses for lugs, I would have thought at least one should have lugs for proper engagement assuming two screws alone to secure the sight were not efficient. What am I missing?
Thanks
Interesting, to be honest, I haven’t had the opportunity to see Riton MPRD yet. On their website they claim that it is a Shield footprint, but based on the description of yours, it think it might be an error. Could you send a photo of the footprint to [email protected]?
I currently have a trijicon rmr on a walther pdp and was thinking about converting over to a holosun. Do you happen to know if I can use the rmr mounting screws or do I need new ones and what length they would be?
Are you referring to the Holosun 407C and 507C models? These have the same mounting standard as the Trijicon RMR, yes. Trijicon RMR comes with longer screws than 407/507C models but I’ve used the screws supplied with Trijicon RMR to mount 407C and 507C red dot sights on adapters designed for the RMR mounting standard on many occasions. Not sure if it works on a Walther PDP, though.
Absolutely PERFECT resource for those trying to make an RDS/mount buying decision, without having to spend HOURS reading half-baked & half-informed articles on the web.
Amazing resource!
I have an RMR pattern 6 second mount. I am trying to see if there is a way I could attach a MICRO footprint optic on it. I have found a RMR to Docter plate and a Docter to MICRO plate, but would you know of any better mounting solutions?
Thank you!
by MICRO are you referring to the Aimpoint Micro mounting standard? If so, I do not know of any converters from RMR to Aimpoint Micro, at least we do not offer any in our online store (yet) https://www.optics-trade.eu/en/.
I have a Sightron SRS-2 red dot sight and need to see the footprint for this sight. The mount for the Burris Fastfire III has 4 posts in the corners and can they be filed down to fit the Sightron SRS-2 sight? Have ordered the Sightron SRS-2 sight from Camera Land….will ship in few days. Do not see the footprint for the SRS, only the STS and RTS. Thanks for any help.
Unfortunately, I have not seen the SRS-2 in person yet. It appears to be quite familiar to the Delta Optical MiniDot HD 24 (the buttons are of the same design):
https://www.optics-trade.eu/en/delta-optical-minidot-hd-24.html
My first guess is the C-more mounting standard but I could be wrong. Here is the drawing of the footprint of the MiniDot HD24:
https://www.optics-trade.eu/blog/delta-optical-minidot-hd-24-footprint/
If that is the case, an adapter plate for the C-more mounting standard will work best.
nice content, was hoping to learn before i read and my expectations exceeded.
nice one!
This is fantastic. I have 3 Burris Fastfires. The # has a top battery cover so no sight removal is needed. I’d like to see which other sights have a top mounted battery cover.
Wow. You spent a lot of time creating this. I recently bought a pistol and have spent hours clicking around the internet looking for some specific/detailed information. Found it!!!!!!
Thank you….
Thank you so much for this site. I was wondering if you had come across any universal plates that can be attached to a variety of bases and allow a variety of mounts to be used?
You are welcome.
Manufacturers such as Toni System and Outerimpact create plates whose upper part is compatible with various mounting standards (it can be modified)

Andraž thank you so much for this extremely informative site!
Looking for a plate to mount a Holosun 507k on a Taurus 101. Similar to Beretta 92/96 but no dovetail for rear sight. The correct plate will need the curved profile of the Beretta slide and will require slide to be drilled tapped.
Does anyone make such a plate?
Apologies, Jeff, I don’t know of such plate. Have you tried contacting Taurus? They might have some more information.
