Weaver #63B One-Piece Scope Mount – Marlin 336, 1894, 1895, 9, 45

The Weaver #63B is a one-piece scope mount engineered specifically for Marlin lever-action rifles. This solid-top design provides a rigid mounting platform for scopes with integral rings, eliminating the alignment issues that can occur with two-piece bases. Built for hunting and field use where reliability matters.

Machined from steel with a matte black finish, this mount fits Marlin 336, 1894, 1895, and the Marlin Camp 9 and Camp 45 carbines. The one-piece construction delivers consistent eye relief and maintains zero under recoil. Mounts directly to the receiver using factory-drilled holes — no gunsmithing required. Accepts Weaver-style rings (sold separately).
