Working on building a rifle here and I've bought the stocks I want........ But all of the deals on barrels are in mid length all of a sudden.... 5.56 or 223 Wylde chamber Carbine length gas system No preference on finish MUST have the pinned A2 fsb (dont care about f-marked or not) New, used... I'll need a gas tube, so if you've got one that's a plus. I can meet in the Portland/Vancouver area. I have cash or might do some trading. Thanks!
