I say sort of because it does technically fire, i pull the trigger, bolt moves and goes pop, but it doesnt fire paint. I try to run paint for it and it doesnt come out the barrel (it not the barrel, .693 bore and the paint goes fine through a .689), i turn the eyes off and it will keep moving the bolt as if its firing normally. It sounds alot quieter than an Ego should. Ive had 2 people quickly look at it and theyve both said they reckon its not getting enough air flowing through it. Its not the dwell i know that much, any ideas?
