Holosun 507 Comp 1x Open Reflex Red Dot Sight – Green Multi-Reticle

The Holosun 507 Comp is an open reflex sight designed for full-size pistols where speed and precision matter most. Whether you're running it for competition, home defense, or duty carry, this optic delivers a clean sight picture and reliable performance shot after shot.

Machined from 7075 aluminum for durability, the 507 Comp features a Shield/RMSc footprint for direct-mount compatibility on a wide range of slide cutouts. The multi-reticle system lets shooters choose between a 2 MOA dot or a 32 MOA circle dot (with or without the center dot), while the solar failsafe and CR2032 battery combo keep the optic powered in virtually any condition.
