Holosun HS515GM 1x 20mm 2 MOA Red Dot/65 MOA Circle Multi-Reticle Reflex Sight - Black Anodized

The Holosun HS515GM is an ultra-durable 20mm micro reflex sight built for hard-use rifle and carbine applications. Machined from a single piece of 7075 aluminum and finished in a low-glare black anodized coating, this optic is engineered to take abuse while keeping its zero on AR-pattern platforms, PCCs, and other long-gun rails.

At its core is the classic Holosun Multi-Reticle System: a crisp 2 MOA central red dot surrounded by a 65 MOA circle with four positioning points, so the shooter can run a precise aiming point for accuracy work or drop into the quick-acquisition circle for close-range transitions. The reticle is illuminated by Holosun's red LED with 12 brightness settings, all powered by a CR2032 battery that keeps the sight running through extended range sessions.

The HS515GM features 1x magnification through a 20mm objective window with unlimited eye relief and multi-layer coated lenses for a clear sight picture in varied light. Windage and elevation are tuned via tactile, tool-adjustable knobs with 0.50 MOA per-click adjustments. The sight ships on a low-profile, locking Quick Detach (QD) mount compatible with Picatinny rails, allowing fast removal and repeatable return to zero.

Holosun's signature Shake Awake technology powers the LED on with motion and puts it to sleep during inactivity, extending battery life. The optic carries an IP68 waterproof and dustproof rating, making it ready for rain, mud, and recoil-heavy duty. Overall length is 3.27" and weight is just 3.74 oz, keeping the package compact and balanced on the receiver.

Whether you're running a duty carbine, a 3-Gun rig, or a home-defense rifle, the HS515GM delivers a rugged, feature-rich aiming solution at a serious value.
