The Holosun 507K X2 Green is a micro pistol green dot sight from Holosun with an M.R.S. (multi reticle system) and a modified RMSc footprint a.k.a. K Series footprint. The MRS reticle gives you a 32 MOA outer ring, and a 2 MOA center dot. The larger outer ring makes “finding the dot” a bit easier, and the 2 MOA dot make precision shots easier to achieve.
This micro pistol optic is designed to fit smaller handguns such as micro compact and subcompact pistols. It will fit on a K series slide directly (like on the Sig P365) but will require an adapter plate to fit on RMSc slides (like the Glock 43X MOS).
The MRS reticle is also configurable, allowing you to use just the 32 MOA circle, or just the 2 MOA dot if you please.
This durable red dot sight is one of the most popular red dot sights Holosun produces. It features a 7075 T6 Aluminum housing, sleek low profile design, side removable battery, shake awake, manual brightness mode, IP67 waterproof rating, 2 nightvision modes, and long battery life ranging from 20,000 to 50,000 hours depending on the reticle and brightness level.
This optic has a green reticle. Green has a few benefits:
- Green reticles are less straining for the eye to see.
- Green reticles can help with astigmatism. If you have astigmatism you will see a blurry dot, we have been told by a few customers that Green dots help with their astigmatism, making the dot look more crisp than the red version.
- Green will not washout on backdrops like green grass, foliage, or green colors.
- In theory Green dots can have a longer battery life because Green is brighter, so for example a green dot on brightness setting 6 may be the same brightness as a red dot on setting 7 – which would save battery life.
