Physical properties

M21 is made for all kinds of military use – it is shockproof, fogproof and waterproof. If you are looking for robustness, this is a top choice – a more robust red dot sight is difficult to find on the market. M21 has got an interesting zeroing method – instead of moving the light source of the red dot you move the whole housing, which is a great feature since it adds to the robustness of the device. The window is very large (diameter of 30 mm) and round which facilitates aiming and allows the user to shoot quickly and accurately. Since the device is made for military use, it can withstand extreme weather conditions. It is also great in terms of aesthetics.

Optical properties

The device’s illumination system works differently during day and during night. The fiber optic collector system powers M21 during daytime, and radioactive tritium in gas form powers it when it is dark. This means that no battery is needed, which is superb. Not having to rely on the battery power is of great importance in hectic and critical situations. The transition from one mode to another is done automatically, according to the surrounding light. In direct sunlight, the red dot is much more powerful than in the dark. Not only can you chose from dot sizes, you can also choose from several reticle shapes when ordering this product (triangle, 4.3 MOA dot, 5.5 MOA dot, Bullseye, Open X). This is one of the rare red dot sights that allows buyer a multiple choice when it comes to the reticle. Triangle, for example, is a great choice – if you zero the device to the upper part of the triangle, you can aim and shoot at long distances very accurately.

Conclusion

Meprolight M21 is not one of the most battle proven red dot sight in the world by chance – its robustness, high-quality illumination system and capability of withstanding extreme conditions contribute to its vast popularity with the military. This has been IDF’s main choice for many years and was thoroughly tested – unfortunately, most of the testing was done during conflicts. We like its zeroing process and illumination system which operates without batteries. Some blue tint can be seen when looking through the optic’s window, which is not that great. The device is also quite big, and the definition of the red dot is not adjustable; however, these are all minor issues which do not void the fact that M21 is an excellent product. Its most important feature is definitely operation without batteries – it always works. In the case of a zombie apocalypse where all the batteries in the world are dead, this red dot sight will remain functional – this is, of course, a statement in jest but a great example of how useful this device actually is. M21 is a must-have for preppers.
