I have an AR-7 .22 rifle by Charter Arms but instead of the plastic floating butt stock, it has a factory wood stock that makes it look like an M-1 Carbine. I could send a picture if I figure out how. I would like to sell this rifle but it seems to be rare and I have not seen any for sale. Did it have a special name, I know the pistol version was different. Any help would be appreciated. Jerry in Idaho.
