Warne 7643M M-Tactical Picatinny Rail for Browning X-Bolt with Mag Base

The Warne 7643M M-Tactical Picatinny rail for Browning X-Bolt with mag base gives you a rock-solid mounting platform built for precision hunting and long-range shooting. If you run a Browning X-Bolt magnum or X-Bolt 2 long/magnum action, this rail delivers the kind of rigid, consistent foundation that makes scope alignment repeatable and eye relief adjustment straightforward—critical when you're glassing at distance or making critical shots in the field.

Every component is engineered for weight savings without compromise. The rail is precision CNC-machined from 7075-T6 aluminum, a material choice that balances strength with the kind of featherweight construction serious backcountry hunters demand. The hardware is black zinc coated for corrosion resistance, and the hardcoat anodized finish protects against abrasion and weather. Self-centering tapered T-15 Torx screws ensure proper alignment every time you mount, and the system is fully NATO-STANAG compatible—so your optics will stay true whether you're shooting factory loads or a custom hand load at altitude.

Available in both zero and 20 MOA configurations, the 7643M is designed specifically for Browning's magnum actions—including the 300 PRC, 300 RUM, and 375 H&H. Unlike generic rails, this one is engineered to fit Browning's exact geometry, meaning no shimming, no guesswork. Built in the USA and engineered for the hunter who understands that ounces add up and precision matters.

Frequently Asked Questions

What Browning rifles does this rail fit?

The Warne 7643M is designed for Browning X-Bolt magnum actions and X-Bolt 2 long and magnum actions. It's engineered specifically for magnum calibers including 300 PRC, 300 RUM, and 375 H&H. This is a firearm-specific mount, so verify your rifle model before ordering.

What's the difference between the zero and 20 MOA options?

The 20 MOA configuration provides pre-angled elevation built into the rail itself, which extends your rifle's effective scope adjustment range for long-range or extreme-distance shooting. Zero MOA keeps the rail level. Choose based on your intended shooting distance and your scope's adjustment capability.

Is this rail compatible with my optic?

The 7643M features a standard Picatinny rail and is NATO-STANAG compatible, meaning any scope rings designed for Picatinny rails will mount to it. Always verify your rings and scope are Picatinny-compatible.

What mounting hardware is included?

The rail comes with self-centering tapered T-15 Torx screws designed to ensure proper alignment. These are black zinc coated for corrosion resistance.
