Question: Will they fit 20mm Weaver rail?
Document: These rings are fantastic. I am using them on a Hatsan Striker 1000S air rifle in .25cal. They fit the weaver rail beautifully, and the screws really hold the rings and scope in place. The construction is definitely capable of taking a beating, as long as your rails hold up.
Love the quality of this item. These are not cheap and don't seem as if they'll ever break.One problem I found when mounting on my rail is that the depth of the mounting bracket/hardware itself was not deep enough to mount to my rail. I'm not sure if it's the design of my specific .22 or these mounts, but luckily my side rails are plastic and I was able to grind the first two notches down with my dremel for these to fit nicely.
I bought these sight unseen because I needed them for my Hammerli Trailside target pistol. These rings fit the .22-sized rail perfectly. My only complaint is they are a bit bulky and heavy for a lightweight target pistol. Otherwise they are a good value and work just fine. Actually, for a lightweight 22 pistol and a lightweight dot-scope, one ring would be plenty. That would cut back on the overall weight.
These rings are used on a variety of .22 rifles from Remington and Marlin. Yes you can spend more but there is no need to! Especially good are the tape inserts - it grips and protects the scope.I currently have rings from Leupold, Burris, Weaver and Warne. They might look a bit better but they do not necessarily work better. Next to try are some rings on my 5.56 platforms, will report next on those!
I got a set of these for my Crosman Phantom because scope kept jumping down the rail and came off! !These have the pin needed to stop this from happing.AWSOME! !
I installed these on my .22 Winchester model 190 and they did the job perfectly. They were easy to install and didn't cost much. I recommend them for anyone in need of rings for a 3/8 dovetail scope rail.
Fits the scope perfect and connects to the rail snug. REALLY like the double screws  on the bottom i have another scope that just has one and doesn't hold. Well made product especially for under 12 bucks  fits smaller rails as well as bigger ones probably.
I purchased these rings to use on my CZ (11mm dovetail)  They are well constructed and solid but not my best choice. The reason is that they grip the rail only at one edge. Not being made specifically for this gun there is a lot of &#34;air&#34; between the bottom of the clamp and the top of the dovetail. They are quite well constructed though for their cost.
The original CenterPoint scope performed fine and has held it's zero for 50 shots on these mounts. Crosman Destroyer 7.9 grain pellets were used exclusively. The reason I tried these rings was for the scope stop in the form of a pin that mates to the hole in the Quest and the 2 rail screws per clamp. Good product at a good price.
I used these to mount a 1" tubeBSA 2X20 Edge Series Pistol Scopeon my Browning 800 Express - 0.220 Caliber spring piston air pistol. This gun has a significant amount of recoil, but these work great in keeping the scope from slipping on the dovetail mounting rail, and they were a perfect for the amount of height clearance I needed.
Answer: yes
