American Defense AD-B2 Cantilever Mini ACOG 1.64" Tactical Scope Mount – Precision Optics Mounting Solution$105.58
Availability: In Stock
The American Defense AD-B2 Cantilever Mini ACOG Mount is a purpose-built quick-release tactical scope mount that solves a real problem: getting your eye properly positioned behind compact magnified optics on the AR platform. If you've struggled with eye relief when mounting a Mini ACOG or similar sight in traditional positions, this one-piece cantilever design moves the optic rearward and elevates it to put your eye in the sweet spot without forcing your head into an awkward position.
Built from 6061 T6 aluminum and finished in hard coat mil-spec anodize, the AD-B2 is engineered to last. The 0.75" reverse cantilever is the key—it extends your optic back far enough to dial in proper eye relief while maintaining a compact overall package. American Defense's patented QD Auto Lock titanium lever system handles both in-spec and out-of-spec rails without fuss, so you're not locked into perfect manufacturing tolerances. The lever can be configured to lock toward the front or rear of your receiver, depending on your setup and preference.
This mount is designed around the 1.5–3x power Mini ACOG platform, including models like the TA33 and TA44, and it also accommodates similar compact prism scopes such as the Sightmark Wraith Mini and Primary Arms GLX/SLX variants. Need to fine-tune the fit? Adjustment requires nothing more than your finger or a flat blade screwdriver—no proprietary tools needed. The mount sits at 2.33" height and plays well with third-party spacers if you want to dial in height-over-bore for your specific rifle.
Whether you're building a lightweight 3-gun rifle, setting up a carbine for tactical training, or just tired of craning your neck to shoot, the AD-B2 brings American Defense's reputation for precision and durability to the compact optics space.
| Manufacturer | American Defense |
| Model | AD-B2 Cantilever Mount |
| Mount Height | 2.33" |
| Cantilever Offset | 0.75" reverse |
| Material | 6061 T6 Aluminum |
| Finish | Hard coat T3 mil-spec anodize |
| Quick-Release System | Patented QD Auto Lock titanium lever |
| Rail Compatibility | Picatinny (in-spec and out-of-spec) |
The AD-B2 is designed for Mini ACOG scopes in the 1.5–3x power range, including the TA33 and TA44. It also fits the Sightmark Wraith Mini and Primary Arms GLX 2x and SLX 1x/3x micro prism scopes. If you're mounting a different optic, confirm that it shares similar footprint and rail interface before ordering.
The 0.75" reverse cantilever moves the optic rearward from where it would sit in a standard mount. This solves the common eye relief problem with Mini ACOGs: it pushes your eye position back so you can achieve a proper sight picture without your face pressed uncomfortably close to the scope, and it elevates the optic overall for better cheek weld and situational awareness.
No. The quick-release lever system and adjustment points work with just your finger or a standard flat blade screwdriver. The lever can be positioned to lock toward the front or rear, and it accommodates both in-spec and out-of-spec rails without requiring specialized tools or fitting.
Yes. The AD-B2 is compatible with third-party spacers, so you can fine-tune height if your setup requires a different sight height or if you're running multiple optics across different rifles.
