The Weaver #418M Top-Mount Scope Base (Weaver part no. 48435) is machined specifically for CVA and Traditions rifles, giving the action a solid, factory-tight platform for a riflescope. Weaver cuts the base from aluminum and finishes it in a black matte to blend with matte-finished barrels and receivers. Because it’s machined to the exact screw pattern of the receiver, there’s no drilling or gunsmithing involved — it bolts straight to the factory holes. This is the correct base to start with if you’re mounting glass on a CVA or Traditions rifle for hunting or target work.

Key Specifications

• Purpose-built to fit CVA and Traditions rifle receivers, matching the factory screw pattern.
• Listed as a 1-piece base, so a single component bridges the full mounting area.
• Uses Weaver’s To Receiver mount style, bolting directly to the factory tapped holes.
• Finished in black matte to blend with matte-finished barrels and receivers.
• Machined from aluminum for a lightweight, corrosion-resistant base.
• Cross-references as Weaver Application #418, matte finish variant.
• Machined to tight tolerances for a custom, snug fit to the receiver.
• Built for maximum ring-clamping strength so mounted rings stay locked down.
• Requires Weaver-style rings to complete the mount (rings not included).

Frequently Asked Questions

Do rings come with this base? No, rings are not included; it requires separately purchased Weaver-style rings.

What’s the difference between this and the standard #418 base? This is the matte-finished version (#418M), built to match matte rather than glossy barrels and receivers.

Will I need to drill new holes to install it? No, it’s machined to match the factory screw pattern, so it bolts directly to the existing holes.
