Drop targets in confidence and reliable precision with the Holosun HS515GM MRS Red 2 MOA Dot / 65 MOA Circle Sight from GunMag Warehouse. Specifically engineered for rifle and carbine shooting applications, this durable, yet lightweight red dot sight features a rugged, anodized 7075 aluminum housing, designed to deliver lasting corrosion resistance and withstand punishing recoil. Push-button controls offer intuitive operation, while the Multi-Reticle System allows you to choose your favored reticle (2 MOA dot, or 2 MOA dot with 65 MOA circle) for improved visibility and lightning-fast field performance, while 12 brightness settings (10 daylight; 2 night vision) deliver exceptional clarity in any lighting. Multilayer reflective glass lenses deflect stray light away from your eye for exceptional clarity and reduced eye fatigue. Operating on a single CR2032 battery (included) this red dot sight boasts up to 50,000 hours of continuous use on the lowest setting. Plus, Shake Awake™ technology automatically activates the reticle when it detects motion for an instant, hands-free activation, and automatically powers down the unit when the weapon is idle for superior battery conservation. Better yet, this lightweight optic includes a quick-release mount. IP67 water-resistant.
