American Defense AD-B2 Cantilever Mini ACOG 1.93" Scope Mount - Precision Optic Mounting Solution
The American Defense AD-B2 Cantilever Mini ACOG scope mount solves one of the most common setup headaches for shooters running compact magnified optics: getting your eye relief right without reinventing your gun. This one-piece cantilever mount raises your Mini ACOG 1.93" above the rail and, more importantly, lets you push the eyepiece far enough back to find a comfortable cheek weld and full sight picture. That .75" reverse cantilever does the heavy lifting, keeping the optic from sitting so far forward that you're forced into an awkward head position just to see through it.
Built from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize, the AD-B2 is designed to last. The patented QD Auto Lock Titanium Lever system grips both in-spec and out-of-spec Picatinny rails alike, so you're not stuck hunting for the one "perfect" rail tolerance. Adjustment is intuitive—no special tools required; your fingers or a flat blade screwdriver will handle it. The lever itself can be configured to lock toward the front or rear of the mount, giving you layout flexibility depending on your rail real estate and handguard clearance.
This mount is engineered for the 1.5–3x Mini ACOG family, including the TA33 and TA44, and will also accommodate the Sightmark Wraith Mini and Primary Arms GLX 2x and SLX 1x/3x Micro Prism scopes. If you run spacers from other manufacturers, they'll work here too, making the AD-B2 a versatile platform for fine-tuning height and eye relief on a modern carbine or precision rifle.
