polishing gauntlet pressure chamber
@ryanroche- There is only 1 o-ring on the valve assembly that is tensioned by the poppit spring return(the silver piece) the main thing to polish(deburr) would be the screw holes that are for the air block, as they tend to cut the block rings upon removal. I have the .22 & .25 & .22 was rough(cut 3 sets of rings before getting it right) If you want to polish, I would focus on Hammer & tube it rides in.
@be4meliz I have ordered new o ring kit and have deburred the screw holes. so I hope that is all in need to do . going out shooting this afternoon. thanks for the info..
