p90 not shooting...
iv read through and tried all the fixes to the related problems, but none have worked... my p90 will simply, not let a bb come out the end of the barrel at more than .000001 foot per second. most the time they just get jammed, somewhere near the hopup.. now, iv tried cleaning the barrel, loosening/tightening the hop up, removing the hop up and making sure its 'crap free' etc, but nothing works... someone told me to check the mechbox to see if there was any air coming out of the front of the nozzle.. none what so ever.. what could/is the problem, and a possible easy fix?
thanks for reading.
