American Defense cantilever ACOG mount by Dustin, Verified Owner, January 25, 2026
These are phenomenal, literally. High enough to clear BUIS sights like KAC, Matech, and my YHM versions, but not so high that your cheek weld is compromised. Helps move the ACOG rearward, solving the bad eye relief we all know they have. As an added ...

Product Info for American Defense Manufacturing Cantilever ACOG Base

The AD-B3-C Mount is a one-piece ACOG mount that places the optic at a 2.1" centerline height. It allows for a rearward position of the ACOG sight while clearing military issued back up iron sights such as the those supplied by KAC / MATECH. The AD-B3-C mount fixes the eye relief issue commonly found with mounting the optic traditionally. The reverse cantilever will allow the user to place the eye piece of the optic much farther rearward without interference. It is precision machined from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize. It features the Patented QD Auto Lock Lever system to accommodate both in-spec and out-of-spec rail systems.image
