Weaver
The Weaver #402 Top Mount Base Gloss in extended length is a precision rifle scope mount engineered for shooters who demand rock-solid optic retention on classic and modern firearms. Built to exacting tolerances, this top-mount base mates with Weaver detachable rings through a square-cut notch design that resists recoil shift—essential when you're running serious glass on a rifle that needs to shoot where it points. The gloss finish fits rifles ranging from vintage Enfield and Mauser actions to modern Savage short and long actions, Parker-Hale bolt guns, and a wide range of other centerfire rifles.
Whether you're assembling a reliable hunting rifle, setting up a milsurp classic, or building a precision shooter from an older platform, the Weaver #402 gives you the secure, repeatable platform that quality optics deserve. The extended base length distributes mounting forces over a longer receiver surface, reducing stress concentration and improving long-term zero retention. If your rifle's drilling and tapping match the Weaver standard—and your action is listed in the compatibility range below—this base will lock down like it was born on that gun.
Weaver has been the standard for scope mounting since before \"tactical\" was a buzzword. Their manufacturing holds to tolerances tight enough that your rings will clamp hard and stay clamped. Pair this #402 with quality Weaver rings and modern quality optics, and you're not thinking about the mount anymore—you're thinking about the shot.

The #402 is drilled for a broad spectrum of rifles including Savage short and long actions (Models 10, 12, 16, 110, 111, 112, 116 and others), Parker-Hale Models 1000–1700, Mauser 98, FN, Swedish 96, Enfield, H&R Models 300/301/330/370, Marlin 455 and MR7, Schultz & Larsen, Sears models, and many others. Confirm your specific rifle model against the compatibility list before purchase, as drilling patterns vary by action.
Yes. The Weaver #402 is designed to work with Weaver detachable rings, which feature the square-cut notch system that mates precisely with this base. Do not use rings designed for other mounting systems.
The extended length distributes the mounting footprint over a longer section of the receiver, which improves rigidity and helps maintain zero under recoil. This is especially valuable on rifles with shorter receiver profiles or on guns that will see hard use.
Yes. When paired with appropriate Weaver rings and a quality optic matched to your rifle and cartridge, the solid engineering and tight tolerances of the #402 provide a dependable foundation for hunting applications.
