Browning Picatinny Rail with Bubble Level — 20 MOA, Matte Black Aluminum
Fits: Browning X-Bolt Ultra Magnum Action (e.g., .300 RUM / .300 PRC)
Cant: 20 MOA (downward bias for long-range elevation)
Interface: Picatinny / Weaver style
Model: 12525 • UPC: 023614950721 • Finish: Matte Black • Material: Aluminum • Feature: Integrated Anti-Cant Bubble Level
Dial in your Browning X-Bolt for serious distance with the Browning Picatinny Rail with Bubble Level (20 MOA). Purpose-built for Ultra Magnum action X-Bolts chambered in long-range performers like .300 RUM and .300 PRC, this lightweight aluminum rail adds the elevation you need to push dope farther—without maxing your turret. The integrated anti-cant bubble level helps you keep the rifle plumb at the shot, improving consistency and reducing windage-induced misses. A matte black finish keeps glare down while blending cleanly with the receiver and optic.
Why This Rail is a Smart Upgrade
20 MOA Built-In: Adds cant to extend your optic’s elevation travel—perfect for zeroing near 100 yards and retaining click range for 800, 1,000 yards, and beyond (with appropriate ammo and optics).
Integrated Bubble Level: Visual anti-cant reference right under your eye line; get level, break the shot, and trust your wind call.
Picatinny/Weaver Compatibility: Accepts a wide range of rings, one-piece mounts, and accessories that use Mil-Std Picatinny or Weaver-style cross slots.
Lightweight Aluminum: Strong yet light to preserve rifle balance; anodized matte black for corrosion resistance and low signature.
X-Bolt Ultra Magnum Action Fit: Designed for Browning X-Bolt Ultra Magnum receivers found on chamberings like .300 RUM and .300 PRC for precise, repeatable alignment.

Real-World Benefits
More Elevation, Less Dial Fatigue: 20 MOA rail preserves turret travel so you can stretch your ballistic curve without shimming bases or holding over.
Cleaner Shot Execution: The bubble level reduces rifle cant that can throw shots left/right at distance—especially noticeable past 400 yards.
Quick, Reliable Mounting: Picatinny slots provide repeatable ring spacing, room for eye-relief tuning, and compatibility with popular long-range rings.
Weather-Ready Durability: Hard-wearing, matte anodized aluminum stands up to rain, dust, and hard travel.
Ideal Applications
Western Big-Game Hunts: Build a confident 500- to 800-yard-capable rig (ethical limits vary by shooter, conditions, and local regulations).
Long-Range Practice & Steel: Track data across distances with consistent cant and secure ring engagement.
Handloads & Dope Workups: Stable, repeatable base for zeroing and validating ballistic solutions.
Installation Guide (Quick Steps)
Unload & Verify Safe. Always clear the firearm before maintenance.
Prep the Receiver. Remove any existing bases; clean and degrease receiver holes and rail hardware.
Set the Rail. Align the 20 MOA rail on the X-Bolt receiver; confirm bubble level orientation is visible from your shooting position.
Torque to Spec. Install with quality screws (and a small amount of blue thread locker if recommended). Torque per Browning/rail instructions—commonly 15–25 in-lb for base screws.*
Mount Optic. Install rings and scope; set eye relief and level the reticle using the built-in bubble and a trusted reference.
Confirm Zero. Bore-sight, then confirm zero at the range and re-check fastener torque after the first session.
*Follow the manufacturer’s torque guidance for your rifle and hardware.
Compatibility Notes
Receiver Family: X-Bolt Ultra Magnum Action only; different X-Bolt actions (short/standard/magnum) can require different bases.
Rings & Mounts: Works with most Picatinny rings/one-piece mounts and many Weaver rings; verify clamp style and height for your scope objective and barrel contour.
Scope Clearance: Choose ring height to clear objective bell and caps while maintaining a natural cheek weld.
Care & Maintenance
Wipe the rail after wet or dusty trips; keep cross slots free of grit for full clamp engagement.
Periodically verify screw torque, especially after rough transport.
Check bubble level visibility and integrity; replace if damaged or clouded.

Frequently Asked Questions
Q: Why do I need a 20 MOA rail?
A: The built-in slope preserves more of your scope’s internal elevation, letting you dial farther without bottoming out—ideal for long-range zeroes and extended shooting.
Q: Will this fit any X-Bolt?
A: It’s engineered for the X-Bolt Ultra Magnum Action. Other X-Bolt actions may require different rails. Confirm your rifle’s specific action length and footprint.
Q: Is the bubble level visible in shooting position?
A: Yes. It’s integrated to be seen from behind the rifle so you can quickly confirm level before the shot.
Q: Are mounting screws included?
A: Browning rails typically include hardware; verify contents on receipt. Use proper torque and thread locker per instructions.
Safety & Compliance
Always follow firearm safety rules. Use an inch-pound torque wrench for installation, and verify zero after mounting or any transport. Observe local laws for hunting methods, shooting distances, and firearm transport.
Set your X-Bolt up for confident, repeatable long-range performance with the Browning 20 MOA Picatinny Rail with Bubble Level (Model 12525, UPC 023614950721)—a lightweight, matte black aluminum base that adds elevation, fights cant, and maximizes your optic’s potential.
