  • 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
  • 1" long
  • .93" wide
  • .24" high
  • .18 oz
  • 2 pieces

  • 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.

Things I liked: This produce solved the issue I had mounting a Vortex Venom sight on my airgun. It is compact and for the most part works well.

Things I would have changed: The fit would be better if the under side of the adapters, between the 2 clamping sides was curved so it fit better on the gun. I have a Hatsan air pistol and a Gamo rifle and bot have the fit problem. It requires that the clamping forces be quite high because the adapter does not seat as well as it might.

What others should know: In spite of the fit issue, this adapter really solves the sight problem I set out to fix which was a red dot sight on an air pistol that was very compact. My shot groupings with the red dot sight is much improved over the original open sights. Being a senior , my vision is not what it was in my teens.

  • SALARIAK from USA asked:

    Are they two pieces? for two rings or a single piece with 2 parts?

    • Tyler from USA:

      Two pieces. Could be made to work with two piece rings or a one piece picatinny mount though.

  • Kevin from USA asked:

    I see a set screw on top. What is that for? Is it the tightening of the scope rings that tightens this adapter on the rail?

    • Chevota from USA:

      I don't have these, no need, but I'd say from looking at the screw is to help keep them from sliding on the rail. I assume it's there because most Picatinny mounts aren't really made to grip well since the crossbar does all the work, so that screw would help somewhat. The poor reviews state what I suspected about their strength. I also suspect many of those were because the adaptor didn't have the adjustment to go far enough for those guns, if so then that little screw would be the only thing keeping the scope from sliding. Not sure why people didn't buy dovetail mounts, unless maybe they have a sight with an integrated mount like some red dots do. They do look cool and I'm sure there are people who are happy they exist, but be sure it'll work for you before you buy. For example I wouldn't put it on a springer unless I modified both of them and the springer. Or if your dove is rounded on top I can't see how they'd fit unless you milled flat spots for them.

  • Eaton from USA asked:

    do these work well? also would they work on the Kral Arms Puncher Pro PCP Air Rifle?

    • Stanley from USA:

      They do what they were designed for ? They make a 11mm into weaver / picatinny.
