Similar to the AD-RECON, the AD-RECON-S mount is made for putting high power glass onto a flattop style AR-15. The AD-RECON-S 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 patent pending Auto Lock™ Lever system to accommodate both in spec and out of spec rail systems.
