The TruGlo 3/8 Inch Dovetail to Picatinny/Weaver Mount Adapter (brand part number TG8953B) converts a factory 3/8 inch dovetail base, common on rimfire rifles, into a Weaver-style mounting platform. Machined by TruGlo from aluminum, the adapter clamps to the existing 3/8 inch base and accepts standard Weaver-style scope rings, opening up a much wider selection of optics and mounts than the original rail allows. The matte black finish matches most rimfire and airgun builds, and all mounting hardware ships in the box. It’s a simple fix for shooters who’ve outgrown the mount options that come standard on a 3/8 inch dovetail rifle.
