The Truglo 3/8" To Picatinny Mounting Adapter transforms a traditional 3/8 inch dovetail base into a modern Picatinny or Weaver-style rail, giving rimfire rifles, airguns, and compatible crossbows a clean way to run contemporary optics. Machined from aluminum and finished in matte black anodizing, this one-piece base offers a solid interface with evenly spaced slots for secure scope or red dot mounting.

This adapter is ideal when you want to upgrade older firearms or crossbows with current optics without replacing the original base. Its integrated adjustable recoil lug and multi-screw clamping system help keep zero under repeated use, making it well suited for range shooting, small-game hunting, and general training. Truglo’s attention to practical design and reliable construction makes this compact adapter a straightforward solution for expanding your mounting options.
