sounds like ur detents might have been moved while dry firing, Try this out
remove bolt, barrel, and hopper
look down the bore of the gun from where the barrel would be
W/ an allen key, tighten ur right detent (the detent on ur right when looking down bore) and tighten it until you see the metal of the detent, then unscrew it to just when the metal goes away (stop when the metal is just a tiny bit gone... basicly, unscrew ti'll u can't see meatal ne more, then unscrew it a TINY bit more)
do the same thing for the other side
and you should be set.
what this does is give u maximum ball detent strength w/out having metal exposed
giving u best results...
also, for some odd reason, my team mates borg just doesn't like halos... i have no clue why.. but meh (he won't let me tinker w/ it
also, what part of florida u in?
