American Defense AD-DELTA-C 30mm Cantilever Mount

The American Defense Mfg AD-DELTA-C is a cantilever scope mount engineered to place high-power 30mm optics forward for proper eye relief on flattop rifles and SCAR platforms. The offset design provides approximately two inches of built-in eye relief while maintaining a 1.5″ optic centerline height for 30mm rings. Precision machined from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize, the mount features horizontal rings and a quick-release attachment system. The patented QD Auto Lock lever accommodates most 1913 Picatinny-style rails for repeatable, secure mounting.
