Tactical Rail Adapter 11mm Dovetail 21mmWeaver

Our Take

An adapter that converts an 11 mm dovetail into a 21 mm Weaver rail — the standard bridge for putting Weaver-clamp optics on dovetail airguns. 90 x 20 mm, 90 g, metal. The useful thing about a longer adapter like this one is that your optic gets a proper mounting surface instead of hanging off a stub. The catch is still the dovetail angle: if your gun’s dovetail is cut differently than the adapter expects, it won’t seat flush and will rock under recoil. Check the fit when it arrives and return it early if it rocks — don’t shim a bad match.
