Still have the parts, and while it is a very heavy rifle for a 20fp power level, the accuracy and shot count might be worth putting them back in.
BUT don't jump on those shot counts, were shooting well past my velocity limits. Are not 40 shot settings. Are more like 30-32 shot settings for the prefered vel. variation.
(as I am the one who refills the gun, why shoot at less than the best the gun can give?).
