Description
The Weaver Mounts 48474 Top Mount Base Pairs are a 2-piece Weaver-style scope base set purpose-built for the Ruger 10/22 rimfire rifle. Machined from lightweight, recoil-resistant aluminum and finished in a non-reflective matte black, this pair provides a solid mounting platform for attaching any Weaver top mount cross-lock ring to the receiver of your 10/22.
Built around Weaver’s classic cross-lock geometry, the bases lock into any compatible Weaver ring for a tight, repeatable fit that holds zero under .22 LR recoil. The 2-piece top-mount configuration installs directly to the factory-drilled and tapped receiver of the 10/22, and the lightweight aluminum construction keeps carry weight to a minimum while standing up to years of range use.
Sold as a pair with rings available separately, this base set accepts all Weaver top mount cross-lock rings and is equally at home on the Ruger 10/22 Charger. It is also compatible with the Ruger 10/22 Mag, 77-22, and 77-50 ML, making it a versatile option across the Ruger rimfire family.
