The AD-B3-C Mount is a one-piece ACOG mount that adds .64" to the overall height of the optic (2" Centerline Height with a 4x32 ACOG). It allows for a rearward position of the ACOG and similar sights while clearing the MBUS PRO back up iron sight. The AD-B3-C mount fixes the eye relief issue commonly found with mounting the optic traditionally. The 2" 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 Titanium Lever system to accommodate both in-spec and out-of-spec rail systems.
**This mount will only clear the Magpul MBUS Pro Rear Sight**
This mount also fits the Sightmark Wraith Digital Night Vision Devices including the HD 2x, HD 4x, 4K, and Mini 4K and Trijicon IR-Hunter Thermal Sight. The washers in the included hardware kit are only to be used for the Sightmark IR scopes (4k, 4K mini, HD, etc)
