Bushmaster upper with Colt rear sight. Upper is in almost perfect condition. Barrel is 20" and is unknown brand but the gunsmith I bought it from new said it was a Douglas. Only markings on it are under the handguards, NB 5.56 1/9 G. FSB is marked M O 4. There is some kind of symbol in the O. I had used the barrel in a FF tube that already had the sling swivel on it so this one has been removed. The muzzle has a recessed target crown and shoots very well. Probably less than 500 rounds through it. Handguards are Colt. Upper does not include B/BC/CH. $215.00 shipped.
