I believe Tim had mentioned the Benjamin 392 & 397's that were shooting poorly. He said he wasn't selling Steroided 392/397, because of their hit & miss accuracy issues.
Members, I recently traded for a Blue streak. took it all apart, cleaned the barrel and tube. had trouble w/my valve. I know i need to replace orings more than likely. what i would like to know from everyone is what else should i do? such as maintenance, replacing parts, modding, can it be deburred so on and so forth. i always wanted a pumper and from the few people i have already talked to, they swear by the benjamin cylindricals. i had SS .20cal sample pack and crow mags grouped very well w/open sights and me sitting on a rail road track supporting rifle with elbow and knee. the next day, they shot like junk. so again, any advice, suggestions, how to's or should do's? any and all help will be greatly appreciated. Thank you,.20cal fan
