Weaver T22 Scope Base Pair Converter for 3/8" Grooved Receiver

The Weaver T22 Scope Base Pair Converter for 3/8" Grooved Receiver is a precision mounting adapter designed for modernizing vintage rimfire and centerfire rifles that feature factory grooved receivers. This converter is essential for shooters and hunters who wish to install contemporary optics on classic firearms without making permanent modifications. It allows for a seamless transition from iron sights to modern scope systems while maintaining the integrity of the original receiver.

Constructed by Weaver, a trusted name in precision optics mounting, this two-piece base set is specifically engineered to fit the 3/8" grooved receiver format commonly found on mid-century rifles. The converter employs a dovetail or groove-locking mechanism to create a secure and repeatable platform that accommodates standard Weaver or Picatinny-compatible rings and scope mounts. Its robust steel construction ensures durability during extended field use and repeated mounting cycles.

Law enforcement armorers, military collectors, and precision rimfire competitors rely on Weaver base pairs to effectively upgrade platform-specific rifles for modern tactical or sporting applications. Installation is straightforward and requires no drilling or tapping, as the bases clamp directly into the existing receiver grooves, making it an ideal solution for those looking to enhance their shooting experience.
