Masterpiece Arms Bolt Action Scope Mount Features The Masterpiece Arms Bolt Action Scope Mount is machined from 6061 T6 aluminum a material chosen for its strength-to-weight ratio and resistance to the stresses of repeated recoil. The one-piece Picatinny-style design interfaces with the rifle s rail to provide positive engagement and its design accommodates both in-spec and out-of-spec rail systems so shooters are not limited to a single rail manufacturer. Multiple locking lugs positioned on the bottom of the rail interface work together to lock the mount firmly in place which is the key to the mount s absolute return to zero performance. This matters most to precision shooters who remove and remount optics between range sessions or when swapping rifles. Built for a 35mm scope tube at a 1.25-inch ring height this mount is sized to clear larger objective lenses common on modern long-range optics. The T3 Mil-spec anodized finish protects the aluminum from corrosion and wear while keeping the mount s weight to just 6.9 ounces. A matte black finish keeps the mount s appearance consistent with most bolt-action rifle setups. Masterpiece Arms built this mount specifically for bolt-action rifles running Picatinny rails making it a solid choice for precision shooters seeking a reliable repeatable optic mounting solution.
