Browning 12524 X-Bolt Picatinny Rail 20 MOA Long Action Bubble Level

The Browning 12524 Picatinny Rail transforms X-Bolt long action rifles into precision platforms with its integrated 20 MOA cant and built-in bubble level. This aluminum rail system addresses two critical accuracy factors: scope mounting angle and rifle cant, delivering measurable improvements in long-range performance.

What Makes This Different

Unlike standard zero-cant rails, this mount incorporates a 20 MOA downward angle that extends effective range by compensating for bullet drop at distance. The integrated bubble level eliminates guesswork in rifle positioning, preventing costly misses caused by shooter cant. CNC-machined from aircraft-grade aluminum, it maintains zero under recoil forces that can shift lesser mounts.

Key Features

• 20 MOA built-in cant extends long-range capability without scope adjustment limits
• Integrated bubble level provides instant visual cant reference
• Matte black anodized aluminum construction resists corrosion and glare
• Direct-fit design for Browning X-Bolt long action receivers
• Standard Picatinny/Weaver rail interface accepts all compatible rings
• Precision-machined mounting surfaces ensure consistent scope alignment
• Low-profile design maintains clean rifle lines

Field performance shows marked improvement in long-range accuracy, particularly beyond 300 yards where the 20 MOA cant becomes advantageous. Competitive shooters benefit from the extended scope adjustment range, while hunters gain confidence on longer shots. The bubble level proves invaluable on uneven terrain or from improvised shooting positions. Weather-sealed construction handles moisture and temperature extremes without performance degradation.
