Holosun 507C X3

The new X3 generation puts the light sensor on the front where it reads brightness at your target, not behind you, so the dot brightness actually matches what you're looking at. Improved glass and 100,000 hour battery life make this the new standard.

Fitment notes: RMR footprint. Open emitter. X3 generation — forward-facing light sensor, improved glass, recessed controls.
