People dry fire X bows all the time.
Seen blown up rig.........one after another coming in my local pro shop the month before the opener.
My guess is that shops w known good limbs, have had their stash long gone.
Dunno if anybody is going to tear down a blown up freebie to keep parts for another customer down the road.
Lots easier to just sell em a new one, with parts they can order if need be.
Not trying to get your hopes up.
Just saying you might be able to get it fixed, but its a long shot.
Because somebody probably blew theirs up and has already depleted local sources of parts.
