Q**O
Works as advertised, thanks.
This is a quality item that grips my Hatsan Mod 25 pistol's 11mm dovetail rails firmly, and I had no trouble mounting Picatinny optics on the top of it. It has three holding screws which is very appropriate for the air guns it will mostly be mounted on (they have intense recoil shocks). The screws are small Torx head for which the vendor supplies the proper "hex" key.My only recommendation would be to make the screws larger in diameter or of high-grade steel. That's because you may want to use loc-tite / threadlocker on them, and even the blue version of that stuff can hold so tight that you won't be able to get these screws out without snapping them off. Don't ask me how I know this.

Not for most shotguns!
I’m giving this five stars, because it appears to be well made and “fit for purpose.” But I bought it for a Beretta shotgun; and the ventilated rib on that gun—and a half dozen other guns I tried it on—is too narrow to mount this rail on it. Matter of fact, I can’t find any similar rail that *will* fit. Smallest they go is 11mm; my rails are 9mm or less. So, be aware!

Nice Adapter!
I wanted to mount a red dot on my Marlin 22 with the dovetail mount. This bolted right on without issue and is very secure.

Fits great but tool is small
Worked very well but the tool that comes with it is too short to crank it down enough. The scope fell off after 10 shots and I had to use a T16 bit to crank it down tighter

Stays tight on rail
fit perfectly on my savage .22. Locks tightly. Have hunted with it for about 6 months now. I rotate sights depending on light. This has stayed tight the entire time. My only regret is not getting a longer rail but that's on me.

Solidly built adapter.
Made of good aircraft aluminum and steel material. Holds firmly on my 11mm pistol railWithout slipping due to recoil. There is a set screw to lock it in place. Very easy to install and comes with a Allen wrench.
