No idea what brand the upper is, built it from another complete Sionics upper. Gasblock is blue loctited in and hasn't walked out of 1,800 rounds or so. Rifling is still crisp. Sorry for the terrible pic, can provide more later if need be.
$450 shipped with the BCM c/h. No BCG.
Gas tube is an aero nitride iirc.
PM for info, no trades, PayPal only please.
