Weaver #S466 Grand Slam Top Mount Base Matte - Precision Scope Mounting Solution

The Weaver #S466 Grand Slam Top Mount Base Matte is a rifle scope mount base engineered for Marlin lever-action and semi-auto rifles. If you're mounting glass on a classic or modern Marlin—whether it's a 336, 1894, 1895, or Camp Carbine—this steel base delivers the solid, repeatable foundation your optics need. Weaver bases are known for their strength and reliability, and the S466 is built to handle the recoil of hunting and range work without shift or creep.

The matte finish resists glare and blends with most rifle finishes, keeping your gun looking purposeful rather than polished. Top-mounted bases like this one sit directly on the receiver and work with Weaver-pattern rings, giving you straightforward, field-proven mounting without complications. Whether you're upgrading a wood-stocked heirloom or outfitting a modern tactical Marlin, the S466 is designed to stay put through seasons of hunting or repeated range sessions.

Installation is mechanical—no gunsmithing required for compatible rifles. Just verify your specific Marlin model matches the compatibility list before ordering. Because these bases are sold individually, you'll need both a front and rear base to complete your mounting setup.

Do I need to buy both front and rear bases separately?

Yes. Weaver bases are sold individually. A complete mounting setup requires both a front and rear base, so you'll need to order two S466 bases.

What rings do I need for this base?

The S466 accepts standard Weaver-pattern scope rings. Make sure your rings are compatible with the Weaver dovetail system.

Will this base work with older and newer Marlin rifles?

The S466 is engineered to fit the Marlin models listed in the compatibility section. Receiver design varies across production years and model lines, so confirm your rifle's model number matches the list.
