hey guys need a little help, for some reason the regulator is coming unscrewed from bottle nipple so the bottle is stuck in my marker and wont come off, luckily there is no air in it, but help? how do i get the bottle off my marker without seperating the reg completely, or is that ok to unscrew that then unscrew the nipple from the asa, btw its a stako bottle stuck into an 06ego thanks rob
