American Defense QD Mount Features The American Defense Mfg. QD Mount is machined from 6061 T6 aluminum and finished in a hard coat T3 Mil-Spec Black anodize for durability under hard use. Its one piece construction is engineered specifically for the Trijicon RMR footprint along with the SRO and other red dots that share the same mounting pattern. The co-witness height places the optic s dot in line with a shooter s iron sights giving a fast and familiar sight picture whether the optic is in use or not. This lightweight design was developed with AR pistols and other compact weapon platforms in mind where every ounce of added weight matters. At the heart of the mount is the patented QD Auto Lock Lever system which locks the mount to a rail without requiring any proprietary tools. The lever can be adjusted with a finger or a flat blade screwdriver and configured to lock toward either the front or the rear of the mount for operator preference. A superior clamping surface ensures maximum engagement with the rail keeping the optic zeroed even after repeated removal and reattachment. The American Defense Mfg. QD Mount is available for sale at GrabAGun in Black for shooters who want fast repeatable optic mounting on their Trijicon RMR equipped firearm.
