I have an RWS M34 in .22 caliber with a Hawke 4X mil dot adjustable objective airgun scope and Hawke mount. It's very important to get an airgun scope and mount with a spring air because they can ruin a good centerfire riflescope, even Leupold occaisionaly. The Mil dots really help with longer range aiming because those .22 pellets drop like a rock when they go past 30 yards. The only negative with my rig is, the elevation will get off sometimes after a lot of shooting because of the barrel droop at the hinge point. This is not a problem with iron sights since they are both attached to the barrel but it is a little annoying when using a scope. If I was doing it a again I would be tempted to get the RWS side cocker .22 pellet gun. Also a pellet pen is a must have item.
