MarkP, that is a negative aspect of the more powerful spring piston air guns. I have a Crosman Phantom of that type in .177. I tried mounting a scope. The unique two way recoil (first recoil in one direction, then the gun switches and recoils in the other direction), though not the type of shoulder punishing recoil of, say, a 45-70 rifle, is easily enough to make your scope mounts slide. I then switched to a mount with a stout steel scope stop pin. That stopped the movement, but the 2 way recoil then destroyed my scope. I removed it and will just ues the open sights. Be careful to get a scope that is made for spring piston air rifles, because you can destroy any standard rifle scope. They are not made for two way recoil, and will not hold up.
MY Phantom's recoil also makes getting tight groups, for me anyway, a rare event. You can read about the "air gun artillary hold" on the web. I can get way more tight groups, and do it way more often, with my Crosman multi-pumps.
Lastly, a spring piston air rifle can be quite loud. Easily could be mistaken for a .22 long rifle. That's not good. A nitro piston system is supposed to be easier on the recoil, and the noise, making them easier to shoot well. There are a lot of shooters, even top smokeless powder shooters, that can't hit the broad side of a barn with a spring piston gun.
Since I want to be able to take out the rat population, and the little critters like to come out after dark, I need a quiet air gun that's accurate enough. If I fired that Crosman Phantom at 9:30 at night, well, I would never do it.
MY Crosman Model 664, and 1322 and 1377 all fit my needs. The 664, I got new for about $40. I tossed the crappt scope it came with, and got a decent 2x7 with adjustable objective, and got a great combination. Reliable, accurate, quiet, inexpensive, doesn't try to look like an "assault weapon".
