i took down the rifle and found a burr at the end of the tube chamber.I took a round file andremoved the burr. the rifle still will not feed the ammo. The carrier doesnt seem to remove the round and carry it up to the breech. While i had the rifle taken down i tried to put a round in the carrier and found it was a very tight fit. Is this fixable without trying to replace the carrier (good luck) or is this now a wall hanger.
