Troy Optic Riser Red Dot Sight Mount 2.26in Black. This can lead to compressing down onto your rifle when engaging threats as you lower your head to your optic and can lead to unintentional tunnel vision. 2.26'' optic mounts relieve this problem by allowing you to keep your head upright for greater situational awareness reaction time and ergonomics while engaging targets. This height also sets your optic at the perfect level for use with helmet-mounted night optical devices gas masks or face shields. Unlike other 2.26'' mounts on the market the Stasis is completely slick. A full-length clamp and two precision machined cross-bolts lock the mount to your rail. TROY inset the locking bolts so there are no additional protrusions to create snag-hazards off the side of your rifle. The Stasis weighs in at only 3.24oz - lighter than other mounts that add ounces with built in BUIS or bulky QD systems. TROY made those redundancy features obsolete with a cleverly designed window beneath the optic mounting surface. Set to co-witness standard height BUIS the Stasis window eliminates the need to deploy folded back-up irons roll your rifle to offset sights or fumble with bulky QD systems if your optic goes down. Simply shift your head down to your fixed BUIS and continue to engage targets as needed.
