if the reg is turned down to far the marker will not cycle.. there are quiet a few o-rings in there. it is possible that one of the is "rolled" the other thing to check is the o-rings on the bolt guide. those get missed 99% of the time becouse they are a pain in the rear to get out..
my primary marker is a slingshot with a nightvision scope
