The AD-B2 Cantilever Mounts are a one-piece Mini ACOG mount that adds overall height and allows for a rearward position of the Mini ACOG and similar sights. The AD-B2 Cantilever mounts fix 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 Sightmark Wraith Mini, and Primary Arms GLX 2x" SLX 1x/3x Micro Prism Scopes. This mount is compatible with other manufacturers 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.Features :Does not require proprietary tools for adjustmentCan be adjusted with your finger or a flat blade screwdriverLever can be configured to lock to the front or the rearPrecision machined from 6061 T6 AluminumHard coat anodized for a lifetime of performanceFully adjustable to fit both in spec and out of spec rail systems"1.64" Height,
