I strongly recommend that you use a 2-piece Weaver scope mount that has 4 screws on each ring cap.

• DN460 scope mount base
• Fits RWS Diana sidelevers…48, 52 & 54…and 460 Magnum underlever
• Attaches to rifle’s 11mm scope rail
• Decreases barrel droop with 17.1″ upward compensation at 30 yds
• Special recoil shock shoulder stops scope shift–forever!
• Hide rifle’s 11mm scope rail; looks professional
• Scope base provides secure scope mounting with Weaver/Picatinny mounts
• 3 hex screws attach base to your Diana rifle
• Includes 2 hex wrenches
