UTG 11mm (3/8") Dovetail to Weaver Adapter, 2pcs
11mm (3/8") Dovetail to Weaver Adapter
Insert into Weaver or Picatinny rings so they'll fit the smaller 3/8" or 11mm rails and dovetails often found on airguns and rimfire guns
If your air gun or rimfire gun has a scope dovetail that measures either 11mm or 3/8" (approx. 9.5mm), you can use this lightweight aluminum adapter to attach your Weaver and Picatinny rings or mount to your smaller 11mm and 3/8" dovetails.
This clever device clips into the base of your Weaver or Picatinny mount (both 1-pc mounts and 2-pc mounts), thereby reducing the size of the clamping jaws on the mount! A very easy way to make your mounts more useful for a wider range of guns. In fact, you can leave your optics in the mounts and move them from gun to gun! You'll still have to resight the gun after attaching the scope, but you won't have to reset or retighten the scope in the mount.
