American Defense Mfg AD-B2 Rear Cantilever Mini ACOG Mount is a one-piece rear cantilever optic mount designed for Mini ACOG and similar micro prism optics. It features a 0.75-inch reverse cantilever to position the eyepiece farther rearward to improve eye relief and a 2.33-inch optical centerline height for a comfortable heads-up shooting position. Precision machined from 6061-T6 aluminum and finished in Type III Mil-Spec hard coat anodize, this mount uses American Defense's patented QD Auto Lock titanium lever for fast, secure attachment to both in-spec and out-of-spec Picatinny rails, without proprietary tools.
