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. More rugged, 8-40 screws increase mount strength by 41%, and are fast becoming necessary equipment on larger caliber rifles.
The LEUPOLD Mark-4 Base - Rem 700 2-pc (8-40 Adaptable) Matte (59230) is the first mount that can accommodate both the beefy 8-40 screw and a modified 6-48 shoulder 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This mounting system features larger through holes that accept the thicker 8-40 screw, and the standard 6-48 screw has been replaced by a shoulder screw to work with the larger opening.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.
The Mark-4 Bases are covered by Leupold's Full Lifetime Guarantee.
