Those used to come on the R9 Goldfinger package. I had a couple of them and never had a problem. However I bought one from PA a few years ago and put it on a RWS 52 and broke it. Bushnell replaced it under warranty and I put it on a rimfire.
I have a Bushnell Trophy 4-12X40 model on a Benjamin gas ram. It was originally on my Beeman R1. Both AG's have a fair amount of recoil. The scope has always worked very well. The Trophy model it is available with the side focus.
I'd be using it on a RWS 34 .22cal that I just picked up on Ebay. This scope is kind of long though. I'm looking for something more compact and lighter so I'm not 100% sure I want the Bushnell. What about the UTG Bug Buster?
