Its a full chrome lined, heavy barrel, with less than 125 rounds down the pipe.
Would like to find a M4A3 upper in a straight across trade, NO B/CH/BC.
Just to get a little more picky, would like it to be a 16 barrel so I don't have to make anything prem. on the end. But I'm really open to all........
Not really for sale, just looking for a trade.
BTW: its the upper on the bottum gun.
Sorry, 1 in 9 and I bought it from Model 1 sales.
