So I have lost ALL hope in Anvil Arms to start/finish building my M4 style upper so I am looking elsewhere. One of the uppers I have come across is made by DPMS (link below). I am not sure on it because it seems that it is a .223 upper...if I am not mistaken, that will not allow me to run 5.56 surplus ammo through it . Another thing is that the barrel is not chrome lined. Ok, I know everyone says to get that but does it REALLY matter? I mean this is pretty much going to be my paper punching plinker and I clean my guns pretty often.
