OK, its a lower priced gun. Someone had a go at lengthening the barrel with an extension, no doubt during the period when this was a way to avoid restricted status. The back sight has been removed; no big deal as long as the receiver hasn't been altered. Bubba has had a go at the front sight, and the stock. There is a cutdown 5 shot magazine in place. From the look of the carbine, I think that it is an earlier M-1 clone. It would seem that the seller considers it to be "used junk", and wisely recognizes that he lacks the expertise to deal in previously owned firearms. If you want a restricted project gun that bubba has had a go at, fine. It could be repaired, but by the time you are done, the investment is going to be more that the gun is worth. If you want a decent M-1, take the sellers wish of good luck in finding what you want.
