Airgun Scope Creep

Need help from the airgunners. I have an older RWS in .177 cal and as I recall it's a Model 34. (Could be wrong on that.) Anyway, I've tried a couple different "airgun" scopes and mounts and no matter how tight I torque the mount screws, the scope creeps backwards a little after each shot. I've even tried torqueing it down to what I think is the point of breaking the screws but still the same result. How can I fix this? Threadlocker on the mount? Threadlocker on the mount and screws? Something else?

Clarification, the mount slides back in the milled groove in the receiver. The scope in the mount is fine.

You need a scope stop on the receiver. It is just a block mounted right behind your rear ring. It keeps the scope from doing that. It is a common issue with springers. My Beeman R1 has had a stop on it since I bought it, and the scope has never moved.

There is a ring company with tried and proven rings for airgunners. I can't remember the co name.

But go to a dedicate airgun forum and they will help you.
 
Check for a scope stop hole in the top middle of your 34 grooved rail. If there is one, that is where the stop screw in most airgun mounts will insert into.
I've had good results with Leapers/UTG one piece mount, it's a pretty good one for the low cost of $15.

^^^ This...mine has one too...
 
Scope stop has been mentioned and that's a good fix. If you have a hole in the top of the rail then make sure that the scope stop has a screw that will screw down and fit into that hole if possible.

And use Blue LocTite on all the screws before you torque them down with a torque wrench. Wheeler Engineering, Inc. makes the FAT WRENCH which is a small hand held torque wrench. It comes with a few different driver inserts but you may have to buy a insert that will fit into the heads of your scope rings and mounting hardware.

I had the same problem with a IGT Gamo Air Gun and it had the hole in the top of the receiver for the Gamo Rings. The Back ring has a screw in the center of it that I was suppose to screw down inside that hole to keep the scope from moving backwards on the receiver after each shot. This was not even a spring type air gun which is said to have even more recoil and harder on rifle scopes. But I still have the problem. My scope was hanging off the back of the rifle before I noticed the problem. I knew that some thing was wrong because my POI was moving all the time and I could not figure out why until I noticed how far the scope had moved on the receiver. Since I put in another scope stop behind the back rings ( with the OM stop) the problem has been solved and I can hit what I'm aiming at.

So the first clue that your scope may not be staying put is when you keep missing the target even after dialing in the scope's reticles. My back rings on the scope has almost come off the receivers rail as it had moved that far. I etched a mark on the top of the rifle's receiver to show me the very back edge of the scope ring and I'll know if the ring is moving now. So far it's staying in place.

Gamo sells a separate scope stop for 3/8" weaver type rails on their air rifles.

I have the Gamo Bone Collector .177 cal single shot break rifle barrel air gun.

I never had to use blue Titeloc on my Crossman 1077 CO2 air rifles. I installed an old scope that I had since the early 1970's on my Crossman air rifles. But I would not buy another Crosman 1077 Air Rifle again. The seals on them start to leak and it cost more to fix the seals that the cost of the Rifle. And I had this happen to two of these Rifles from Crosman.
 
I have a Benjamin and it has a hole in the top and the back ring has a pointed screw that you run down to keep the scope from creeping back.
 
There are good mounts with a stop pin. I have liked the Beeman I think 5030. Even use them on my .22 rifles, very stout.
On many of my air rifles there is a back screw on the scope rail. I take this out and replace it with a longer screw and a cone shape washer or large head screw and cone washer. it then sticks up just enough to act as a stop.
