Response to Custom shop 2400 carbine showed up today.....
If you have the plastic front sight then everything needs to line(transfer port to barrel port and muzzle flat 180 degrees from barrel port)b/c the plastic front sight is indexed by the muzzle flat. The fancier muzzle brakes are not indexed by the barrel, so if crosman screwed up the machining, then you can just re-align the barrel port and the transfer port and seperately align the muzzle brake.
