The Holosun 507C X2 ACSS Vulcan Red and Green Dot Sights are specialty optics co-created with Primary Arms for full size and compact pistols. They come with an RMR footprint and feature a 250 outer ring and a 10 MOA chevron reticle. The purpose of the 250 MOA outer ring is to help you "find the chevron" when drawing the pistol. The 250 MOA outer ring is only visible when you do not see the chevron reticle. When the chevron is centered the outer ring is not visible. This acts like an aim assist to help you adjust your grip quickly to get on target faster. Learn more about the ACSS reticle here.

The 10 MOA Chevron gives you an extremely precise aiming point, and also acts as a rangefinder.

They come with shake awake, have a solar failsafe with auto and manual brightness mode, are IP67 waterproof, and have a 25,000 hour battery life. They have 7075 T6 aluminum housings and clear glass and come with a limited lifetime warranty.
