The Weaver #S35 Grand Slam Top Mount Base is a matte-finish rifle scope mount base engineered for precision rifles and hunters who demand rock-solid optic mounting. This front base is part of Weaver's time-tested two-piece mounting system and pairs with a matching rear base (typically the S36 or S40A, depending on your rifle) to deliver the stable platform your scope needs for hunting, target shooting, or long-range work. Built from high-strength steel, the S35 handles the recoil and vibration of centerfire rifles without shift or flex, giving you the confidence that your zero stays true.
The S35 fits a wide range of popular rifle platforms, from classic Remington 700 actions (both long and short) to Howa 1500s, Mossberg 1500-series rifles, Weatherby Mark V and Vanguard models, and many others. Whether you're mounting glass on a time-honored hunting rifle or a modern precision build, Weaver's straightforward base design works across generations of firearms. The matte finish resists glare and complements any rifle stock or chassis.
Installation is simple: the S35 uses standard Weaver-pattern holes and fastening, so if you're familiar with base mounting, you'll be up and running quickly. Because this is a front base, you'll need to order the compatible rear base separately—check our compatibility guide or give our team a call if you're unsure which rear base matches your rifle. Once both bases are torqued down and your rings are mounted, you're ready to dial in your scope and head afield.

The S35 is designed as a front base for many popular rifle platforms, including Remington 700 (long and short action), Howa 1500, Mossberg 1500/1550/1700, Weatherby Mark V and Vanguard, Ruger 77 Round Top, and various other modern and vintage actions.

Yes, the S35 is a front base only; you must order a matching rear base separately. Most rifles pair the S35 front with an S36 rear base, though some rifles with extension rails use the S40A rear. Verify which rear base matches your rifle before ordering to ensure proper fit and hole alignment.
The S35 uses the standard Weaver hole pattern, so any Weaver-compatible scope rings will work. This gives you flexibility in choosing rings that match your specific scope tube diameter and mounting height preference.
Yes. Weaver's high-strength steel bases are engineered to provide the stable, repeatable platform that long-range and precision shooting demands, provided you pair it with the correct rear base and properly torque all fasteners.
