Holosun HS515CM 515 1x 20mm 2 MOA Red Dot/65 MOA Circle Black Anodized

The Holosun HS515CM is an ultra-durable 20mm micro reflex sight purpose-built for hard-use rifle and carbine applications. The housing is machined from 7075 aluminum with a corrosion-resistant black anodized finish, and the optic carries an IPX8 waterproof rating so it keeps functioning through submersion and harsh field conditions.

At the core of the HS515CM is Holosun's Multi-Reticle System (MRS), letting the shooter choose between a crisp 2 MOA red dot alone or a 2 MOA dot inside a 65 MOA circle for fast close-quarters acquisition. The LED reticle is parallax-free with unlimited eye relief, and brightness is controlled across 12 daylight settings via side-mounted buttons. Both Solar Failsafe, which keeps the sight running on ambient light when the battery is depleted, and Holosun's motion-activated Shake Awake technology are built in.

Internally, the sight is powered by a single CR2032 battery rated for up to 50,000 hours of runtime on setting 6. The optical window is multi-coated for a bright sight picture, and the turrets deliver 0.50 MOA per-click adjustments for windage and elevation. At just 3.53 oz and 3.34" long, the HS515CM adds minimal bulk to a rifle or carbine rail.

The sight ships mounted to a 1.63" quick-detach (QD) mount, allowing tool-free removal and solid return-to-zero. Designed for rifles and carbines, the HS515CM delivers Holosun's full feature set - Solar Failsafe, Shake Awake, MRS, and IPX8 sealing - in a compact, ruggedized package.
