HS515GM can be quickly detached from the rifle because of its QD mount. It is equipped with a Killflash filter that eliminates compromising reflections from the objective lens. Clear glass flip-caps help protect the lenses from abrasion and blows.
HS515GM is strikingly similar to HS515CM but does not have a solar cell built in. It is IPX8 certified, meaning that it is protected against continual water submersion. Shake Awake function works like a charm. It is made from aluminium with a hard anodized finish. Windage and elevation turrets are shrouded and thus protected from potential blows. HS515GM has turrets with 0.5 MOA per click (15 mm at a distance of 100 m).
HS515GM’s shrouded windage and elevation turrets are a great idea since these parts are very exposed and can get damaged by unexpected blows. Shake Awake works really well – switching from “sleep mode” to “active mode” happens in an instant. When the optic no longer detects movement, it is put back in “sleep mode” to prevent unnecessary energy loss.
