American Defense AD-B2 Cantilever Mini ACOG 1.54" Tactical Scope Mount - Precision Optics Accessory

The American Defense AD-B2 Cantilever Mini ACOG mount is a one-piece precision solution for shooters running compact magnified optics who need better eye relief and a higher sight line. If you're mounting a Mini ACOG—like the TA33, TA44, or compatible prism sights from Sightmark or Primary Arms—and find yourself struggling with eye box positioning or cheek weld consistency, this cantilever design pulls your optic rearward and up to solve those ergonomic headaches. The .75-inch reverse cantilever geometry gives you the breathing room to position your eye piece where it actually works for your face and shooting style, without the traditional mounting interference that plagues compact optics.

Built from 6061 T6 aluminum and finished in hard coat mil-spec anodize, the AD-B2 is engineered for longevity in the field. The cantilever stays rigid under recoil and environmental stress—this is precision-machined stuff, not stamped approximations. What sets American Defense apart is the Patented QD Auto Lock Titanium Lever system. It accommodates both in-spec and out-of-spec Picatinny rails, which means your mount will clamp down securely whether your rifle's receiver is textbook perfect or has the real-world variation that exists in the industry. No proprietary wrenches required; adjust with your finger or a flat blade screwdriver.

The 1.54-inch height is a thoughtful middle ground—enough elevation for a proper sight picture over most rail systems and handguards, but not so tall that you're awkwardly high on the scope or running into rail-mounted accessories. The lever can be oriented to lock toward the front or rear of your rifle depending on your setup and how you manage your controls. This is smart, practical engineering for shooters who demand reliability and function from their mounting solutions.

The AD-B2 is purpose-built for Mini ACOG scopes like the TA33 and TA44. It also fits the Sightmark Wraith Mini and Primary Arms GLX 2x and SLX 1x/3x Micro Prism Scopes.

Will this mount work on my rifle's rail if it's not perfect?

Yes. The Patented QD Auto Lock Titanium Lever system is fully adjustable to secure the mount on both in-spec and out-of-spec Picatinny rails, so you don't need a flawless receiver to get a solid clamp.

Do I need special tools to adjust or install the AD-B2?

No. The mount can be adjusted with your finger or a flat blade screwdriver. No proprietary tools are required.

Can I adjust the height with spacers?

Yes. The AD-B2 is compatible with other manufacturers' spacers if you want to customize the final sight height beyond the standard 1.54 inches.
