The Warne Mountain Tech Browning X-Bolt Magnum rail is a tactical Picatinny-style base for the X-Bolt Magnum and the X-Bolt 2 long and magnum actions (Warne part no. 7643M). Warne lists it for magnum actions including the 300 PRC, 300 RUM and 375 H&H. Warne machines it from 7075/T6 aluminum and finishes it in a Mil-Spec hardcoat anodize with black zinc coated hardware. Self-centering tapered T-15 Torx screws seat it on the receiver. A hunter running a heavy magnum can mount a scope on a rigid base that adds only 2.5 ounces.

Key Specifications

• The rail fits the Browning X-Bolt Magnum and X-Bolt 2 long and magnum actions, so the base matches the longer receiver.
• Warne lists the 300 PRC, 300 RUM and 375 H&H as magnum actions it fits, which tells a buyer the long action size is covered.
• Construction is CNC machined 7075/T6 aluminum, an alloy chosen for strength at low weight.
• The finish is a Mil-Spec hardcoat anodize, which resists abrasion and corrosion.
• Bases use black zinc coated hardware for protection from the elements.
• Screws are tapered 6-48 with a self-centering T-15 Torx drive, so the base centers itself as it is torqued.
• The top surface takes Picatinny and Weaver style rings and is NATO-STANAG compatible.
• Weight is 2.5 ounces, a small addition to a magnum-weight rifle.
• The rail is designed and made in the USA as a firearm-specific fit.
