Have had all the variants of the Rn10 through to the mk 3 pro target the later being the best out of the box.
Currently shoot a steyr , once I got the barrel cleaning right and the right pellet for the barrel, it was a accurate
As any of the air arms , but the reg is a different thing fps, when the right person had his hands in it the air arms, aa was better. 4 fps variant,STEYR can't touch it. Lock time on the other hand STEYR hands down balance as well. Horses for courses. For half the price I would go for the AA.
Make sure it has a good reg.
