Nightforce Optics Steel One Piece Scope Mounting Base with 40 MOA Taper

• Nightforce One Piece Steel Bases: An integral recoil lug machined on the bottom of the base provides a precise fit when bedded to the rifle's action, preventing any movement of the base or recoil stress on screws holding the base to the receiver. • Our one-piece bases are machined to exact Picatinny Mil. Std. 1913 specification rail dimensions. This design allows the same scope to be used on several different rifles, always optimizing eye relief. Choose from 20 or 40 M.O.A. tapers. Designed for right-or left-hand actions, our bases will never interfere with loading or extraction.
