American Defense AD-B2 Cantilever Mount 2.33″

The AD-B2 is a one-piece Mini ACOG cantilever mount designed to add overall height and position a Mini ACOG-style optic farther rearward on the rail. The .75" reverse cantilever addresses common eye-relief issues by allowing the eyepiece to sit rearward without interference. It is precision machined from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize for durability.
