The Warne Skyline Precision Cantilever Mount has been engineered from the ground up with the MSR rifle shooter/competitor in mind. Machined from 7075 T6 aluminum billet, and featuring 2 integral recoil lugs along with 4 mounting crossbolts, the precision mount easily handles the rigors of competition or hard use environments while being at the ideal 1.54" height for AR type receivers. A generous 2" cantilever provides optimal eye relief. The STANAG rail interface allows for more precise mount alignment and return to zero capability than a traditional Mil Spec 1913 Picatinny interface, still being compatible with all picatinny rails. The Warne Skyline Precision Cantilever Mount features a wide assortment of accessories that mount directly to 10 different locations on the scope rings.
