It is not very accurate even after cleaning the barrel and getting the paint out of the muzzle. the crown looks alright though so i just gave it a quick polish. Ive tried numerous pellets even and it wont group anything.. i decided i'd keep it anyways though and just use it for testing valves. So i go and add a third pin to the pumparm and now that it doesn't flex anymore the stupid thing wont close all the way the groove that fits it to the tube isnt deep enough. will someone with some wood tools help me out with this or recommend a tool for the job?
