The Weaver Tactical Extended Multi-Slot Picatinny Base for Remington 783 Long Action gives you the mounting flexibility modern rifle optics demand. Built on a 6061 T6 aluminum platform with a durable matte Type III hard coat anodize finish, this base extends 1 inch forward compared to standard mounts, opening up real estate on your receiver for larger objective lenses, better eye relief positioning, or dual-ring setups. Whether you're running a long-range hunting rig or a tactical bolt gun, the multi-slot Picatinny pattern accepts both Picatinny and Weaver-style rings without compromise.
The engineering is straightforward and proven: an integral recoil lug locks the base down, while hardened Torx screws resist stripping under recoil. That forward extension isn't just a gimmick—on a 783 Long Action, it genuinely matters when you're trying to co-witness iron sights, mount a cantilever ring, or simply get your scope positioned where it needs to be. The matte finish plays well with modern tactical rifles and won't throw glare like polished aluminum.
Weaver designed this base specifically for the 783 platform, so fit and drilling are dialed in from the factory. If you anticipate pushing your shots past 600 yards, a 20 MOA cant version is available separately for added elevation adjustment range—a smart option for long-range hunting or precision rifle work.

Frequently Asked Questions
Will this Remington 783 Picatinny base work with my existing scope rings?
Yes—the multi-slot Picatinny pattern is compatible with both Picatinny and Weaver-style rings, so you can use rings you already own or swap them as your setup evolves.
What does the 1 inch extended forward length actually do for my rifle?
The extension moves your mount forward on the receiver, which clears room for larger objective lenses, improves eye relief positioning, and gives you more options if you want to add iron sights or run a dual-ring configuration.
Should I get the 20 MOA cant version for my 783?
The 20 MOA cant is useful if you plan to shoot beyond 600 yards regularly and want extra elevation adjustment range built into the base itself. The standard zero cant works fine for typical hunting ranges and in-field shooting; choose based on your actual shooting distance and scope specifications.
Is the base designed specifically for the 783 Long Action?
Yes—this base is engineered specifically for the Remington 783 Long Action, so drilling and fit are factory-optimized for that platform.
