American Defense Manufacturing AD-B2, Quick Detach Mount Review

First Impressions of American Defense Manufacturing AD-B2, Quick Detach Mount

The American Defense Manufacturing AD-B2, Quick Detach Mount promises to solve a common problem for shooters using mini ACOG-style optics: achieving proper eye relief on modern sporting rifles. This one-piece cantilever mount is designed to push the optic rearward, addressing the “nose-to-charging-handle” issue many encounter with traditional mounting solutions. American Defense Manufacturing (ADM) is a known name in the industry, so my expectations are high. The AD-B2, with its patented QD Auto Lock Titanium Lever system, offers a quick detach capability that should make swapping optics a breeze.

I was constantly struggling with eye relief on my AR pistol when using a Primary Arms GLx 2x prism scope. Traditional mounting placed it too far forward for comfortable and consistent use. I needed a solution that was robust, reliable, and, most importantly, allowed me to quickly switch back to iron sights if needed.

Upon unboxing, I immediately noticed the solid construction and clean anodized finish of the AD-B2. It felt substantial without being overly heavy, inspiring confidence in its durability. The QD lever felt incredibly sturdy and engaged with a satisfying click. Compared to cheaper QD mounts I’ve used in the past, the AD-B2 exudes quality and precision. I was considering a Larue Tactical mount, but the ADM’s lower profile and lighter weight appealed to me more. I also looked at a Scalarworks option but found the American Defense Manufacturing AD-B2, Quick Detach Mount better suited for my specific prism optic due to its height and cantilever design.

I was excited to see if the American Defense Manufacturing AD-B2, Quick Detach Mount would live up to its promises of solving my eye relief issues. It had the potential to transform my AR pistol into a much more usable and enjoyable firearm. My initial impression was one of cautious optimism.
