Black Rain Ordnance
The Browning X-Bolt 20 MOA bubble level scope base is built for shooters who demand rock-solid accuracy from the moment they mount their optic. This precision rifle scope mount combines a purpose-built 20 MOA elevation platform with an integrated bubble level, giving you the tools to set up a square rifle and level reticle without reaching for extra gear. Whether you're dialing in at the bench, working up loads, or setting zero in the field, that bubble level keeps you honest—eliminating guesswork and helping you catch mounting mistakes before they cost you a shot.
Built from aircraft-grade alloy, the X-Bolt base is engineered for durability and repeatable performance. The mounting platform uses four screws per base (eight total) to lock your rings down with serious rigidity. This four-screw-per-base design spreads load and vibration across a larger footprint than lighter alternatives, which matters when you're running a precision gun hard.
The Picatinny-style mounting standard makes it compatible with both Weaver-style and Picatinny-style rings, so you're not locked into a single ring ecosystem. If you already run Weaver or Picatinny rings on other guns, this base will work with them—no need to rebuy components just to fit a new rifle.
This is a no-frills mounting solution for hunters and shooters who appreciate precision engineering. No unnecessary features, no marketing fluff—just a solid base that does what you ask of it.
| Brand | Black Rain Ordnance |
| Product Type | Scope Base with Integrated Bubble Level |

Yes. The Picatinny-style mounting platform is generally compatible with both Weaver-style and Picatinny-style rings, so you can use existing Weaver rings if you have them on hand.
The 20 MOA built-in elevation allows you to use more of your scope's vertical adjustment for long-range shooting, extending your effective range and giving you finer adjustment resolution at distance. This is especially useful for magnum calibers and extended-range hunting.
Yes. The integrated bubble level helps you set up your rifle square and level during initial scope mounting and in the field, reducing setup errors and helping ensure consistent shot placement.
Four screws per base, for eight screws total. This heavier fastening pattern provides superior rigidity and load distribution compared to lighter two-screw designs.
