I have just aquired an auto cocker but I have little idea of how to maintain it normally. Other than the obvious cleaning and oiling of the bolt and the outside pieces and the barrel is there a good way to keep the marker in tip top shape, i don't have a huge budget and i am no prepared to completely strip the thing without expert guidance. I only bought the thing for £265 with air and a revolution hopper, so you can tell my budget is not large as that was all i could spare for a marker.
