Leupold Mark 4 Base Winchester 70, Short Action, 1 Piece, 20 MOA, Matte Black Md: 170748
Leupold mounts are every bit as rugged and dependable as the Leupold optics they’re intended to secure. With a huge variety of mounting systems, for nearly every type of firearm under the sun, you’re sure to find the perfect match for you firearm, and your style of shooting.
Leupold’s Mark 4 8-40 Adaptable Mount - Also available in a 20-MOA Long-Range Shooter version - is the first mount that can accommodate both the 8-40 screw and a modified 6-48 shoulder screw. Larger through holes accept the thicker 8-40 screw, while the standard 6-48 screw has been replaced by a shoulder screw to work with the larger opening. This gives 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 screws.
- Fits: Winchester Model 70
