American Defense AD-B2 Cantilever Mini ACOG Mount - 1.41" Height, Precision Optics Support

The American Defense AD-B2 Cantilever Mini ACOG Mount is a one-piece cantilever mount purpose-built to solve a common problem: eye relief and sight picture positioning with compact magnified optics on modern rifles. This 1.41" height mount moves your Mini ACOG rearward on the rail while lifting it higher, eliminating the cramped eye box and awkward cheek weld that comes from traditional sight placement. Whether you're running a TA33, TA44, or other compact prism and magnified scopes, the AD-B2 gives you the breathing room to shoot comfortably and accurately.

Built from 6061 T6 aluminum and finished in hard coat Mil-Spec T3 anodize, this mount is engineered to last a lifetime of hard use without losing zero. The .75" reverse cantilever design is the key to its flexibility—it lets you position the eyepiece farther back than conventional mounts allow, which is especially valuable on short-action rifles, AKs, or any platform where rail space is tight or ergonomics demand rearward optic placement. The mount works with Mini ACOG scopes including the TA33 and TA44, and also fits the Sightmark Wraith Mini and Primary Arms GLX 2x and SLX 1x/3x Micro Prism systems.

American Defense's Patented QD Auto Lock Titanium Lever system handles both in-spec and out-of-spec Picatinny rails, so you get a rock-solid mount no matter the rifle. Adjustments require only your finger or a flathead screwdriver—no proprietary tools, no hassle. The lever can be oriented to lock toward the front or rear of the mount, letting you customize fit and handling to your setup. This mount is also compatible with aftermarket spacers if you need to fine-tune height or cant.
