Hawke Sport Optics Frontier Reflex Red Dot Sight 3 MOA Dot Weaver/Docter Footprint Black. Premier reflex sights built for supreme accuracy functionality and durability. Frontier Reflex sights are constructed from high-grade aluminum and include a steel shroud kit for ultimate protection under hard daily use. Featuring premium wide view optics Frontier is designed for daily carry competition and duty pistols while being equally brilliant on AR s and hunting rifles. The built-in Docter footprint is extremely popular for direct installation to pistols and rifles while the supplied low-profile Weaver/Picatinny base offers limitless mounting options. A slide-out battery tray with captured retention screw allows easy battery replacement without removing the sight or needing to re-zero. Easily cycle between manual and auto-brightness modes at the press of a button to perfectly suit any lighting condition. Manual mode features a 10-stage brightness control including 2 night-vision compatible settings and built-in A.I.M. (Auto Illumination Mode) which conserves battery power by putting the sight into a standby mode when no movement is detected for 2 minutes. The sight automatically powers-on immediately when it senses movement. In auto-brightness mode an onboard sensor constantly adjusts the dot brightness appropriate for the ambient light. Paired with an ultra-high efficiency LED emitter Frontier can operate at a daylight-bright setting for over 5 years on a single battery.
