Similar to the AD-RECON-S, the AD-RECON-SL mount is made for putting high power glass onto a bolt action rifle. This is the lowest mount that AMD offers. The AD-RECON-SL is a straight up scope mount with no eye relief built in. 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. Mfg: American Defense Manufacturing
