These are unique, sharp looking barrels. You would never know they are blems since the Cerakote covered up some Parkerizing errors. Also, the Colt roll marks are not at 12:00, but off to the sides. 100% functional. Chromed lined Colt steel barrels.
This barrel is the 10.3" thick SOCOM profile (without M203 cuts), very much like the 11.5" FBI profile, but this barrel is 10.3," in the thick profile. This is new old stock, 2015 Colt manufactured. This is not a cut-down.
Factory Colt marked, "C MP 5.56 NATO 1:7" and date stamped. Standard Colt chrome-lined, to last almost forever, and that includes throwing it in the mud. Comes ready for a flash hider of your choosing, with standard 1/2-28 threading. Front sight base with drilled and pinned a-frame sights.
This barrel is an great upgrade for a Mk18 Mod 0 build, or for a custom short barreled rifle.
This barrel left the Colt factory as a 10.3" barrel. Our friends at Potomac Armory have installed and timed an M4 extension, and re-drilled the gas port to be the correct 0.070" port for the ultra-short gas system. But, somewhere along the way in finding the timing of the M4 extension and drilling the gas port there were some cosmetic imperfections. These barrels were some of the first. You might call them guinea pigs. Some of the barrels had some blemishes in the phosphated steel, and some have the gas port drilled off-center, where the gas port does not line-up with the Colt roll marks. Nothing whatsoever wrong with the gas port, just the cosmetics of where the roll marks are. Some are at 11:30, others at 2:00, etc.
