I dont mean to insult your intelligence, but after the first break (in breech and up feedneck) you DID clean everything out thoroughly right?its in the breech then blown upto feedneck.
tried three different paints. one of them being spec ops (bloody hard).
pulse works fine on rail and an ion.
i tried upping bip, lowering rate of fire, dwell and input preesure.
i will keep tweaking till i get it.
