Browning X-Bolt Base/Ring Gloss Low Mount X-Lock .400" Standard Height

The Browning X-Bolt Base/Ring Gloss Low Mount X-Lock in .400" Standard Height is a one-piece integrated scope mount system built for hunters and shooters who demand rock-solid optics stability. Unlike traditional two-piece bases and rings that can develop play or misalignment over time, this unified design combines the base and ring into a single rigid assembly machined from 7000 series aluminum. The result is a mount that eliminates the connection points where slippage happens, keeping your scope locked in zero through recoil and rough handling in the field.
Browning designed these mounts specifically for X-Bolt rifles, and the X-Lock system ensures compatibility and proper fitment. The standard .400" height works for most rifle setups and scope combinations, giving you plenty of clearance without excess elevation. The gloss black finish matches modern rifle aesthetics and resists reflections that could give away your position. All hardware is included—eight mounting screws secure the unit to your rifle, with dedicated fasteners for the base and ring so everything stays put.
Whether you're mounting a hunting scope for deer season or a target optic for the range, this base/ring system takes the guesswork out of alignment and delivers the stability serious shooters expect. The 7000 series aluminum keeps weight reasonable at 6.4 ounces while maintaining the rigidity needed for reliable performance across calibers and shooting disciplines.
