Hey everyone, just wondering what how you mount scopes to dovetail mounts. I have a 22lr with dovetails and noticed that the scope had moved forward after a day at the range. I had this problem before with my pellet gun having dovetail mounts and I just bought a dovetail to weaver scout mount adapter and that fixed the problem. I have a couple of solutions to this but I want to hear what would you guys would recommend.

option 1: 1 piece dovetail scope mount with stop/locking pin

option 2: 2 piece dovetail scope rings with stop/locking pin

option 3: dovetail to weaver scope base mount with stop/locking pin & a set of weaver scope rings

I have used nothing but Weaver Tip-off 3/8" factory .22 dovetail rings on several .22's since about 1965. Usually real Weavers, but also Redfield, Browning, and even Tasco on occasion.

Never had a scope slip on a .22 yet.

I would venture your rings are out of spec, or you didn't de-grease them and have them tight enough.
You can also put a drop of Blue Lock-Tight under the clamp feet for extra insurance if you want too.

As for air-rifles?
U.S. uses Weaver Tip-Off 3/8" grooves on 22 rifles.
European and Chinese made air-guns & older foreign .22's use 11mm grooves.

Yes I know, 11mm and 3/8" is the same, but they are not the same.

There was a time when Beeman and other reputable air-rifle places sold real 11mm rings for air rifles. Some of the better ones even included a steel recoil stop pin that fit a hole in the ring and a matching hole in the receiver.

Today, not so much, as everyone seems to sell 3/8" .22 rings and call them air-rifle rings.

After looking into this very thing myself I am opting for the one piece BKL for both the Marlin .22 and something along the same lines on a RWS model 48 .22 air rifle.
Most of those rings that come with rimfire scopes are pretty much crap anyway.
