Yes I traded in my Steyr Pro X last week for a .22 Impact MK2 at Braces and so far it has been spot on. Whoever had it before me had not tightened the barrel properly so would presume that's why they traded it back in (the grub screw was just about to fall out so the barrel was moving which is probably why they had traded it back in) This is my 3rd Impact and I must be one of the lucky ones as I have never had a problem with any of them. My .177 X barrel Impact now has a Pard 008 LRF night scope on it which is superb. That Impact has had probably in excess of 10,000 pellets through it and not missed a beat.
