The AD-SCOUT mount is made for putting high power glass onto a flattop style AR-15. The cantilever throws the scope out front, allowing you to get the right eye relief. It is precision machined from 6061 T6 aluminum and finished in hard coat T3 Mil-Spec anodize. It features the patented Auto Lock™ Lever system to accommodate both in spec and out of spec rail systems.


Street price on this mount is around $150.
