SPF WTS complete upper 20" chromed lined 1/7 twist no ban with bayonet lug/ A2 FH. Barrel is Gov't contoured.
Barrel marked CMP, bolt carrier has "C" stamp, I believe bolt itself is also Colt. Upper has no markings. Overall excellent I got this on a trade so I don't know the round count. Can e-mail pics on request. Not looking for trades. $375 shipped OBO.
Correction edit: A2 upper has broken "A" mark.
