One-piece scope base gives long range shooters an additional 25 MOA of elevation. Helps preserve scope internal adjustment by keeping the crosshairs in the center of the adjustment range. Integral recoil shoulder provides additional shear strength on heavy recoiling rifles. Each base is hardened and stress relieved before machining. All critical dimensions and clamping surfaces are CNC machined to tolerances as close as .0003". Made to MIL-STD 1913 Picatinny specifications.
SPECS: 400 series stainless steel, black (BL) or natural (SS), finish, matte. Approx. 6½" (16.5cm) long. Includes 6-48 Torx mounting screws.
