Browning Base AB3 20 MOA Short Action Scope Mount

The Browning Base AB3 20 MOA Short Action Scope Mount is a Picatinny rail base purpose-built for shooters who demand precise zero and unwavering reliability. Whether you're running a precision rifle at distance or zeroing a new setup for hunting season, this short action mount delivers the elevation adjustment needed to dial in high-velocity rounds without eating up turret adjustments on your scope. The 20 minutes of angle pre-cant gives you more usable elevation range, especially valuable if you're stretching shots beyond typical hunting distances or want to hold zero for multiple ammunition loads.

Built from high-strength aluminum alloy, the AB3 base is engineered to handle recoil and environmental stress without shift or failure. Its four-screw design ensures a solid mechanical lock to your receiver, with no slop or wobble once properly torqued down. The Picatinny top profile accepts both Weaver-style and Picatinny-compatible rings, giving you flexibility in your ring selection without hunting for an adapter or different mounting system.

If you're building or upgrading a short action rifle—whether it's a .308, 6.5 Creedmoor, or similar platform—this mount bridges the gap between a flat base and a high-angle option, letting you use modern scope designs without sacrificing versatility. Installation is straightforward; it's a direct receiver attachment with no gunsmithing required on standard Browning short actions.

Frequently Asked Questions

What rifles does this Browning base fit?

The AB3 is designed for Browning short action rifles. It attaches via four receiver screws and is not compatible with long action receivers or other manufacturer platforms without custom fitting.

What scope rings work with this 20 MOA Picatinny mount?

Any ring designed for Weaver or Picatinny rails will mount to this base. The rail profile accepts both standard ring types, so you have flexibility in your ring choice.

Why choose a 20 MOA base instead of a flat base?

The 20 minute angle pre-cant provides additional elevation adjustment range, useful for long-range shooting or when dialing for ammunition with higher ballistic coefficients. It lets your scope turrets stay in a usable adjustment window rather than topping out.

Does this come with rings or screws?

This product is the base only. Scope rings and mounting hardware are sold separately; verify ring compatibility (Weaver or Picatinny) before ordering.
