The Weaver #421M Top-Mount Scope Base (Weaver part no. 48444) is machined specifically for the Remington Model Seven, giving this compact bolt rifle a factory-tight platform for a riflescope. Weaver cuts the base from aluminum and finishes it in a black matte that matches the Model Seven’s factory finish. Because it’s machined to the exact screw pattern of this rifle, it bolts straight to the factory holes with no drilling or gunsmithing needed. This is the correct base to start with if you’re mounting glass on a Model Seven for a lightweight hunting rig.

Key Specifications

• Finished in black matte to match the Model Seven’s factory finish.
• Machined from aluminum for a lightweight, corrosion-resistant base.
