Will this rail fit my original generation Browning X-Bolt rifle?

No, the Leupold BackCountry Rail model 188018 is specifically engineered only for the Browning X-Bolt 2 Long Action receiver. It is not compatible with short action models or the original generation Browning X-Bolt receivers due to differences in action and screw-spacing geometry.

What type of scope rings can I use with this cross-slot rail?

This rail features a versatile universal cross-slot design that is fully compatible with both Picatinny- and Weaver-style scope rings. For a seamless setup, you can pair it with matching mounts such as the Leupold Backcountry Ring Mount 30mm.

How heavy is the rail and what material is it made from to handle tough Australian bush conditions?

The rail weighs just 2.4 oz, making it exceptionally lightweight for long-distance backcountry hunting trips across Australia. It is CNC-machined from premium aircraft-grade 7075-T6 aluminum, providing superior strength, heavy-recoil durability, and an anti-glare matte black finish that resists corrosion.

What is the recommended installation torque specification for the base screws?

For a secure and stable installation on your Browning X-Bolt 2 Long Action, the recommended base-to-receiver screw torque is 22 in-lbs. This ensures the single-piece rail remains rigid under heavy-recoil conditions.

Scope Base - Leupold LE188018 X-Bolt 2

The Leupold BackCountry Cross-Slot Scope Base Browning X-Bolt 2 LA 1-pc Matte (MPN: 188018) is a premium, ultra-rigid mounting solution engineered specifically for the Browning X-Bolt 2 Long Action (LA) rifle receiver. This single-piece rail serves as a secure, uncompromising link between your rifle and your optic, ensuring consistent accuracy under the most demanding field conditions. It is important to note that this base is designed precisely for the screw-spacing geometry of the second-generation Browning X-Bolt Long Action receiver, meaning it will not fit short action receivers or original first-generation Browning X-Bolt models.

Key Features:

Aircraft-Grade Construction: CNC-machined from premium 7075-T6 aluminum, providing significantly higher strength and shear resistance than standard 6061-grade aluminum alloys.
Cross-Slot Versatility: Features a universal cross-slot design that is fully compatible with both Picatinny- and Weaver-style scope rings, allowing for flexible eye-relief adjustments.
Ultralight Profile: Weighs only 2.4 ounces (approximately 68 grams), keeping your overall rifle setup lightweight for long-distance carry in the field.
High-Recoil Stability: The rigid one-piece design distributes recoil forces evenly, ensuring your optic remains securely zeroed even when firing heavy long-action calibers.
0 MOA Cant: Designed with a flat 0 MOA elevation, making it ideal for standard hunting and medium-range shooting applications.
Matte Black Finish: Features an anti-glare anodized matte black finish that prevents game-spooking reflections and provides robust protection against corrosion and environmental wear.

Who It Is For:

This scope base is built for Australian hunters, sports shooters, and alpine backcountry enthusiasts who own a Browning X-Bolt 2 Long Action rifle and require a dependable, lightweight mounting platform. It is particularly suited for those traversing rugged terrains, such as the Victorian High Country or remote outback locations, where reducing gear weight is crucial but sacrificing structural integrity is not an option. Because it is a passive mechanical accessory, this rail requires no batteries, power sources, or electrical certifications, making it a reliable and low-maintenance upgrade that complies fully with local Australian firearm accessory regulations.
