Two things an AG scope needs. Focus to a reasonably close range. I'd say 25 Yards minimum but 10 yards is better. The focusing error created by different eye positions behind a scope that is NOT focused on the distance being shot will make a lot of airguns seem a lot less accurate than they can be. This is called parralax error and it can be illustrated fairly easily. If you place the scope on a solid work surface so the scope can look down range at a number of objects at different distances. You will notice the crosshairs stay fixed on the point where the scope is really focused and eye postion will not change the cross hairs off the POA. At distances the scope is NOT focused at the cross hairs will move all over the target and POI will be different with different eye positions at the back even though the scope nd target is stationary.
The other is generally considered the task of more picky shooters, using the scope in the middle of it's range, by using drooper mounts will yield better tracking(erector spring under normal tension) and extend ranges to reach out and still be able to click to the Impact point.
The Airgun scopes that can tolerate springer recoil and go down to 10 yards can essentially go on about anything made. I never see them break if they are in a solid one piece mount, but I see them break all the time in split rings and mounts with rings that can rotate around the mounting base.
