Leupold Rifleman Gen2 1-Piece Scope Base Matte Black Aluminum - Ruger 10/22

The Leupold Rifleman Gen 2 is a one-piece scope base purpose-built for the Ruger 10/22, giving rimfire shooters a reliable, factory-engineered mounting platform for their optic of choice. Part of Leupold's value-oriented Rifleman line, this base delivers the brand's quality and tolerances at an accessible price point, making it a smart upgrade over factory iron-sight mounting or budget aftermarket bases.

Machined from aluminum and finished in a low-glare matte black, the base is built to hold up to years of range time and field use. The integrated 1-piece design provides a strong, repeatable mounting surface that helps your scope hold zero under recoil and preserves a consistent scope-to-bore relationship - critical for accurate rimfire shooting at varying distances.

Installation is straightforward: the base drops directly onto the Ruger 10/22 receiver's factory drill pattern and is secured using the included screws. Leupold specifies a base/receiver screw torque of 12-15 in-lbs (as specified by Ruger) for proper installation. Once mounted, the base accepts any standard rings (sold separately) sized to your scope tube - 1-inch for traditional rimfire scopes, or 30mm rings for larger-objective hunting and varmint optics.

Like every Leupold product, the Rifleman Gen 2 base is backed by the company's Lifetime Guarantee - if it ever fails due to defects in materials or workmanship, Leupold will repair or replace it for as long as the original purchaser owns the product. Whether you are building a plinker, a small-game rifle, or a precision 10/22 for competition, the Leupold Rifleman Gen 2 1-piece base gives your Ruger a rock-solid foundation for your optic.
