The Weaver #402 Scope Base Set (Weaver part no. 48108) is machined for the High Standard, Marlin 455, and Marlin MR7, giving these bolt rifles a factory-tight platform for a riflescope. Weaver cuts the two-piece set from aluminum and finishes it in a black gloss that matches most factory blued receivers. Because it’s machined to the exact screw pattern of these rifles, it bolts straight to the factory holes with no drilling or gunsmithing needed. This is the correct base set to start with if you’re mounting glass on a Marlin 455, Marlin MR7, or High Standard rifle.
