Thanks for the info chaps keep it coming
Regards the airwolf, hand on heart it's the best rifle i've ever owned It does everything I want it to do and im still highly impressed with it, the shot count is superb, and I know its one of those 'yeah would say that cos you own one etc' but I will always tell it how it is.
I bought a rapid7 before the wolf because it was recommended to me as the rifle to have etc and at first I was impressed with it, but that gradualy wore off, the lack of any quick fill and gauge started to slowly put me off it, removing the buddy bottle all the time was becoming a chore and then I started to have seal problems and leaks with it which put the nail in the coffin.
sold it and bought the wolf I use it for hunting and target shooting down my local range in my view and from my experiences its highly recomended and everything its cracked up to be
