AD-B2-C Cantilever Mini ACOG Mount-(2209)

The AD-B2-C Mount is a one-piece Mini ACOG mount that adds .64" to the overall height of the optic (1.5" Centerline Height with the Primary Arms 3x SLx Prism). It allows for a rearward position of the Mini ACOG and similar sights while clearing the MBUS PRO back up iron sight. The AD-B2-C mount fixes the eye relief issue commonly found with mounting the optic traditionally. The .75" reverse cantilever will allow the user to place the eye piece of the optic much farther rearward without interference. This mount is ideal for the 1.5-3x Power Mini ACOG Scopes, such as the TA33 or TA44 and will also fit the Nvision Halo LR thermal scope, Sightmark Wraith Mini, and Primary Arms GLX 2x, SLX 1x/3x Prism Scopes. This mount is compatible with other manufacturer's spacers. It is precision machined from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize. It features the Patented QD Auto Lock Titanium Lever system to accommodate both in-spec and out-of-spec rail systems.

**This mount will only clear the Magpul MBUS Pro/ MBUS 3 Rear Sights and MI Combat Rear Sight**
