Weaver
The Weaver Tactical Extended Multi-Slot Picatinny Base for Browning AB3 Long Action is a purpose-built mounting solution designed to maximize your optic and accessory mounting options on this popular platform. Built from 6061-T6 aluminum and finished in matte black, this one-piece base extends forward by 1 inch compared to standard offerings, giving you significantly more real estate on your rifle's receiver for positioning your scope, red dot, or other tactical gear exactly where you need it. That extra inch can make the difference between a cramped setup and a properly balanced, ergonomic rifle build—especially if you're running a longer optic or want to leave room for a front-mounted accessory.
The extended design works within Weaver's proven multi-slot Picatinny system, meaning you're not locked into a single mounting footprint. Whether you're setting up a long-range hunting rifle, a tactical carbine, or a precision target gun, this base gives you the flexibility to dial in your sight picture and weight distribution. The 6061-T6 aluminum construction handles recoil and the rigors of field use without unnecessary weight, and the matte finish resists glare and plays well with modern tactical aesthetics.
Installation is straightforward for anyone familiar with receiver-mounted bases, but if you're new to rifle optics mounting, having a gunsmith or experienced shooter verify zero and alignment is always a smart move. This base is engineered for the Browning AB3 Long Action specifically, so fit and function are dialed in from the factory.

Yes. The multi-slot Picatinny pattern accepts any standard Picatinny-rail rings, mounts, or accessories. This flexibility lets you choose optics and gear independently of the base itself.
