Holosun HS507COMP is a rugged open-reflex sight featuring a durable anodized 7075 T6 aluminum housing with IP67 dust and water protection, and a reliable loading capacity up to 5000 G.
The sight offers a large 22x28 mm window with 1x magnification, parallax-free aiming, and unlimited eye relief for fast target acquisition under all conditions. Its Competition Reticle System (CRS) includes a 2 MOA dot and 8, 20, and 32 MOA illuminated red circles, providing versatile aiming options tailored to precision and speed. Brightness is easily adjusted across 8 levels (6 daytime, 2 nighttime) to match lighting scenarios perfectly.
Powered by an easily accessible side-mounted CR1632 battery, the HS507COMP incorporates Shake Awake technology — extending battery life up to 50,000 hours by activating the sight only when in motion. The compact size of 46x33x33 mm and weight of 48 g allows quick installation, directly on an RMR compatible plate, and zeroing.
This model delivers high performance in tactical, airsoft, and hunting applications where quick, precise target engagement and rugged durability are essential.

Why Choose the Holosun HS507COMP?
Upgrade to the HS507COMP if you need a pistol red dot that survives brutal field abuse while delivering split-second precision. Its 7075 T6 aluminum housing takes 5000G shocks and IP67 seals out rain or dust during extended hunts or CQB drills—far tougher than budget plastic sights that fog or crack under pressure.
The CRS reticle switches seamlessly: 2 MOA dot for surgical shots at 25m, or 8/20/32 MOA circles for rapid close-range acquisition in dynamic airsoft or tactical scenarios. Shake Awake wakes it instantly on movement, stretching CR1632 battery life to 50,000 hours—change it once a year, not mid-mission. Parallax-free 22x28mm window and unlimited eye relief mean no re-zeroing after bumps, with 8 brightness levels matching dawn patrols to noon sun.
At 48g and RMR-compatible, it mounts in seconds on pistols or PCCs without bulk. Trusted by pros for zero holdover in recoil-heavy strings, it's priced competitively at Professional Optics. Install: torque to 15 in-lbs, zero at 10m with 5-shot groups, wipe clean with lens pen.
