Leupold Mark 4 Picatinny-Style Scope Base, Browning A-Bolt LA 20 Moa 1-Pc (8-40 Adaptable) Matte 170751

The first mount that can accommodate both the beefy 8-40 screw and a modified 6-48 shoulder screw. Features larger through holes that accept the thicker 8-40 screw, and standard 6-48 screw has been replaced by a shoulder screw to work with the larger opening. This will give you the flexibility to mount your rifle with the common 6-48 screw size, or drill and tap your gun to accept the 8-40 screw. These new bases will fit Winchester PBR, Remington SuperMagnum, HS precision, and other 8-40 rifles without modification.
