The Browning Base AB3 20 MOA Long Action Scope Mount is a precision receiver base built for hunters and long-range shooters who demand reliable optics mounting on their Browning rifles. This aluminum alloy base features 20 minutes of angle of elevation—a popular choice for shooters who want to dial in elevation at distance without eating up turret rotation. Whether you're threading a scope for 300-yard deer hunts or stretching shots past 500 yards, that 20 MOA head start gives you usable elevation in the scope's main turret when you need it.
The base attaches securely to your receiver with four screws, providing the solid, repeatable platform you need for accuracy. Construction from high-strength aluminum alloy means it'll handle the recoil and environmental punishment that comes with serious hunting and shooting. The 1913 Picatinny interface accepts both Weaver-style and Picatinny-style scope rings, so you're not locked into a single ring ecosystem—use what you already own or choose rings based on fit and function rather than mounting compatibility.
If you're building or upgrading a long-action Browning and want a no-nonsense base that won't drift or shift, this is the kind of component that simply gets out of your way and lets your scope do its job.
| Brand | Black Rain Ordnance |
| Product | Browning Base AB3 |
| Elevation | 20 MOA |
| Material | Aluminum alloy |
| Mounting Interface | 1913 Picatinny |
| Ring Compatibility | Weaver and Picatinny-style rings |
| Attachment | 4 screws |
Yes. The AB3 uses a 1913 Picatinny interface and accepts both Weaver-style and Picatinny-style rings, so compatibility is broad. Check your rings—if they mount to either standard, you're good.
The 20 MOA tilt built into the base gives you extra elevation adjustment built into the mounting surface itself. This lets you zero your scope without maxing out its turret, preserving scope adjustment range for longer shots and making it easier to dial distance corrections at the range or in the field.
This base is designed for Browning long-action rifles. The four-screw attachment is specific to Browning receiver geometry, so verify compatibility with your specific model before ordering.
