ok so my gun had some issues. i fixed most of them. but now my lpr seems to be inconsistant(I had an issue getting goos readings off my tester) and when I fire the gun fast, it makes a puff sound.
its sort of like half cycle noise as if i was holding the bolt back. it happens about every 20 shots at 15 bps. if i hold my bolt back it doiesnt do it(like with my finger). and it i 1 ball it doesnt do it.
i never took out my schrader valve of my lpr cause i have no clue how to get it out. could this be the issue? i know your supposed to clean the orings in there not just on the piston.
