Below are the Holosun 507 Comp Red & Green dot sights. These are offered at the best price with free shipping.

The Holosun 507 Comp is a competition pistol red dot sight with a large window. These optics have a Trijicon RMR footprint, so they will mount to any RMR footprint slide, or adapter plate.

Their window is very large compared to traditional pistol red dots. The reticles also come with the CRS System (Competition Reticle System). This gives you a 2 MOA Dot, and then a combination of an 8, 20, or 32 MOA outer ring.
