Leupold 1-Piece Mark 4 8-40 Adaptable Steel Scope Base 20 MOA – Savage 10/110 Round Receiver SA – Matte Black

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.

Large caliber rifles are becoming more and more popular with today_s shooters. Mounting large riflescopes on these firearms with conventional 6-48 screws is not ideal as the increased recoil and scope weight can over stress screws and lead to possible failures. Updated more rugged 8-40 screws increase mount strength by 41 percent and are fast becoming necessary equipment on larger caliber rifles. Leupold is proud to announce a mount that can accommodate both the oversized 8-40 screw and a conventional 6-48 screw.

This mounting system features larger through holes that accept the thicker 8-40 screw and the standard 6-48 screw has been replaced by a shoulder screw to work with the larger opening.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 screws.

ADAPTABLE MOUNT FEATURES: Will accept 6-48 shoulder screws and new 8-40 screws. Both 6-48 shoulder screws and 8-40 screws are included (6-48 shoulder screws are stronger than standard 6-48 screws). 8-40 screws are 41 percent stronger than standard 6-48 screws.
