View Full Version : Bolt Blowby !

I cant stand the puff of gas out of the feed port every time I shoot, does the bolt need a 3rd O-Ring up front ? Or what ?

You could drill some gas relief holes in the feedneck so the gas will go out the sides rather than up into the hopper. But it does help the paint fall in gravity hoppers because of the jarring of the paintballs - it shakes them loose. Alamo City Paintball sells MR1 bolts that have a variety of options - they have an anti-chop bolt and delrin bolts with zero or multiple o-rings (you can pick how many and color!). This might help your problem.
