I guess something has changed at T/C over the years. Back in the mid 90's I bought one of their firehawk inlines and had some blowback concerns. The guy sent me a whole bunch of parts, and some from the newer model Black diamond to try. I then proceeded to break a thimble screw while trying to mount the sling swivel to it, they sent me a bag of screws, some new thimbles, swivels, and for some reason a few flamethrower nipples, all of this came real fast and real free. I'm sorry to hear they have gone down hill.
BTW: That inline makes a dandy groundhog gun with Harris bipods :-)
