Similar to the AD-RECON-S, the AD-RECON-SL 20MOA mount is made for putting high power glass onto a flattop style AR-15 or bolt action rifle. Features 20 MOA of added elevation adjustment built in to the base. This extra adjustment is great for long range shooting. This is a straight up mount with no forward offset and is the lowest mount we offer. The arrow marking on the mount will point toward the muzzle when mounted. 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. For 30mm rings.
