The American Defense AD-RECON scope mount has many advantages that very few others provide. Its patented QD Auto Lock lever system does not require proprietary tools for adjustment. The lever can be locked on both the front or the rear of the mount. Additionally, the lever can be adjusted with just a flat head screwdriver or even your finger. AD-RECON scope mounts are made of the highest quality materials to allow a lifetime warranty. Made in the USA, AD-RECON mounts come from precision machined 6061 T6 aluminum. The hard coat type 3 Mil-spec anodize ensures a lifetime of performance. These quality 40 MOA mounts were designed to put high-powered optics onto an AR-15. The cantilever throws the scope out front, allowing the shooter to get the right eye relief. American Defense was founded on the premise of hard work, and this AD-RECON scope mount shows just how much effort is put into every product.
