American Defense AD-B2 Cantilever Mini ACOG 1.64" Tactical Scope Mount – Precision Optics Mounting Solution

The American Defense AD-B2 Cantilever Mini ACOG mount solves a real problem: getting proper eye relief with compact magnified optics on modern rifle platforms. This one-piece tactical scope mount uses a 0.75-inch reverse cantilever design to push your Mini ACOG or similar sight rearward on the rail, extending your eye relief and eliminating the cramped head position that comes with traditional mounting. The 1.64-inch overall height gives you clearance above the receiver while maintaining that low-power optic advantage for close-to-intermediate range work.

Built for shooters who run magnified prism scopes and compact ACOGs on AR-platform rifles, the AD-B2 handles the TA33, TA44, Sightmark Wraith Mini, Primary Arms GLX 2x, and Primary Arms SLX 1x/3x Micro Prism Scopes—and it'll accept other manufacturer spacers if you need further customization. American Defense machined this from 6061 T6 aluminum and finished it in hard-coat Mil-Spec anodize, so it'll survive hard use without babying. The standout feature is the Patented QD Auto Lock Titanium Lever system, which actually works with both properly-spec'd and slightly out-of-spec Picatinny rails—no forcing, no cursing, just a solid mount that adapts to reality.

Adjustment and setup are straightforward: no proprietary wrenches needed. You can dial it in with your finger or a flat-blade screwdriver, and the lever configures to lock toward the front or rear depending on your setup and preference. Once locked, it stays put. This is the kind of mount that says "I've been in the game long enough to engineer what actually works," not just what looks aggressive in a catalog photo.

Frequently Asked Questions

What optics does the AD-B2 cantilever mount fit?

The AD-B2 is designed for Mini ACOG scopes like the TA33 and TA44, and will also mount the Sightmark Wraith Mini and Primary Arms GLX 2x and SLX 1x/3x Micro Prism Scopes. It's compatible with other manufacturer spacers if you need to adapt different optics.

Why use a reverse cantilever mount instead of a standard mount?

The 0.75-inch reverse cantilever design moves your optic rearward on the rail, extending eye relief significantly. This solves the cramped viewing position and eye-to-scope distance issues that often come with mounting compact magnified optics in the traditional forward position.

Does the AD-B2 require special tools to install and adjust?

No. The lever can be adjusted with your finger or a flat-blade screwdriver—no proprietary wrenches or specialized tools needed. The lever itself can be configured to lock toward the front or rear depending on your setup.

Will this mount work on out-of-spec Picatinny rails?

Yes. The Patented QD Auto Lock Titanium Lever system accommodates both properly in-spec and slightly out-of-spec rail systems, so you're covered on most modern AR-pattern rifles.
