Leupold BackCountry Cross-Slot Scope Base Ruger 10/22 - 20 MOA LU176389

Every shooter knows the moment: you’ve tuned your Ruger 10/22, tested dozens of ammo types, and refined your hold. You can feel the rifle’s potential, but when that target stretches beyond the horizon, your scope’s adjustment falls short. The difference between a “pop” and a “ping” can be 200 yards, and at that distance, every fraction of an MOA matters. To reach your full long-range potential, you don’t just need a mount—you need an advantage.

The Leupold BackCountry Cross-Slot Scope Base for the Ruger 10/22 delivers that advantage. Designed with precision and performance in mind, this base provides a built-in 20 MOA of elevation, giving you the adjustment range needed to dial in first-round hits without relying on holdover. Every shot is more predictable, every adjustment more intuitive, and every target within reach.

Crafted from 7075-T6 aluminum, this one-piece base combines strength and light weight, ensuring it won't compromise your rifle’s balance. Made in the USA, it’s built to the same rigorous standards as Leupold optics, delivering a secure, unwavering link between your scope and rifle. The Cross-Slot design provides maximum flexibility, accommodating both Picatinny- and Weaver-style rings, so you can mount your preferred optic with confidence.

This base isn’t just a convenience—it’s a necessity for serious Ruger 10/22 enthusiasts. Precision rimfire competitors, varmint hunters, and long-range plinkers will all benefit from the 20 MOA cant that lets you fully utilize your scope’s turret adjustments. By removing the need for “Kentucky windage,” the BackCountry Cross-Slot Base ensures every shot is as precise as your preparation allows.

Installation is straightforward, with the base designed to match Ruger specifications and recommend a torque of 12-15 in-lbs. At 5.8 inches in length and weighing only 1.75 ounces, it adds minimal bulk while maximizing performance. Whether you’re stretching the limits of a rimfire rifle or chasing the perfect long-distance group, this base is the foundation that turns potential into performance.

Leupold’s commitment to quality and reliability shines through in every detail. From the durable 7075-T6 aluminum to the cross-slot versatility, this base is built to last a lifetime, just like the optics it supports. Take control of your trajectory, eliminate guesswork, and elevate your shooting with the Leupold BackCountry Cross-Slot Base.
