JRC is awesome with warranty, definitely contact them and see what they say. As for mine I've never noticed any problems, but they also do recommend you run them wet.
Since you can see where it's wearing off, check where that mates to and you may find a burr or sharp edge.
Try to return the rifle before doing anything? I wouldn't mess with it.
Good to hear! I hate hearing that anyone is having problems with this carbine, because mine has run flawlessly so far.
