Mark 4 8-40 Adaptable Mount:
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 percent, and are fast becoming necessary equipment on larger caliber rifles. Leupold’s Mark 4 8-40 Adaptable Mount 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This mounting system features larger through holes that accept the thicker 8-40 screw, and the standard 6 48 screw has been replaced by a shoulder screw to work with the larger opening.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.

MARK 4 8-40 Adaptable Mount Features:

  • Accepts both 6-48 shoulder screws and 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)
  • These bases will fit Winchester PBR, Remington Super Magnum, HS Precision, and other 8-40 rifles without modification (some firearms will not work with these adaptable mounts – check current offerings for details)
