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. Weaver-to-11mm or 3/8" Dovetail Adapter
  • 1" long
  • .93" wide
  • .24" high
  • .18 oz
  • 2 pieces
  • 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

I got for my Aspen PCP a 3X12/44 mmAO scope that has a 30mm tube, came with medium high Weaver mounts and I needed a way to mount it to the 11mm dovetail on the gun. These adapters did the trick. Not only did they allow me to use the mounts that came with the scope, they raised the scope up to a level that fit my eye.

Pros
Easy to use.

Cons
Just didn't know what the little setscrews in the adapters were for so I removed. No problems so far.

You need it great price if you dont want to replace the mount that the scope come with. Make sure you take the set screw off and line it up like mine.

Pros
Great Quallity and good price

They worked just fine but I wouldn't like to mount them on higher recoiling springers because they could come loose. I usually put them on my c02 pistols where thereis no recoil.

Pros
A good way to mount weaver type scope mounts on 3/8 and 11mm rails.

Cons
I wouldn't put them on springers if I didn't have to but you can, if you take care tightening the screws

I have several scopes that I like to swap between guns and this eliminates the problem of having Weaver style mounts on a scope that you need to mount onto either a 3/8 or 11mm sized mount on a gun.

Pros
Easy fix to a common problem. Easy to install, not expensive, you can still use your Weaver style mounts on either a "Dovetail" 3/8 or 11mm mount.

Cons
It relies only on how tight you tighten the screws of the scope's mount as it just slips into the scope's mount and is held there only with the springs in the mount itself until you tighten the screws on the scope mount, which clamps it onto the gun and also secures it in the scope's mount. (so you can't just leave it on the gun itself..)

This one adapter have a little problem, if you don't tight it hard as hell, it will fall apart, it happens to me in a Benjamin Trail NP pistol, I put a CenterPoint red/green dot open reflex, and I don't tight it well, after a few shots the entire sight falls to the ground.

Pros
Very easy to use Low price If tighten well it works

Cons
A little weird design, screws can be difficult to tight if you need them to be one after the other If you need more contact surface this is not the way to go
