Hi All!
I've got a Colt AR-15 A2, HBAR SPORTER, serial number 214XXX with a barrel that is stamped underneath the handguards.
Barrel Stamping reads as follows:
ST MIL-B-1159SE CMV 5.56 NATO 1/7 CL HP MP
There are no other markings on the barrel.
I've read that early Model 6600s were made with Knight barrels.
Just trying to figure out a barrel make, specifically if it's original.
Thanks,
Rob
