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 08/15. 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. Included standard barrel nut and FSB, and accepts lower or side-mounted sling swivels (but none included)
This barrel is an great upgrade for a Mk18 build, or for a custom short barreled rifle. yes, it will fit under M4 handguards or a RAS rail.
This barrel left the Colt factory as a 10.3" barrel, but it was designed to be installed in Colt's proprietary monorail system. 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.
Note: We have a limited supply of these thick-profile barrels, and they come to us in batches. If we are out of stock, put you name on the list to be notified when the barrels come to Charlie's warehouse.

Note on Colt 10.3" & 11.5" barrels: Charlie's offers a variety of choices for the collector, clone-builder, law enforcement officer and shooting enthusiast.
We take special care in bringing you the best in short barrels, and use the best artisans, both in-house, and in our extended supply chain, when something has to be engineered to a Colt production barrel. Our collectors and cloners will want the 10.3" barrel for historical accuracy. The Daniel Defense is a great option, as it is now being used by US Special Forces in limited numbers, and is readily available and affordable. For more authenticity, choose a Colt 10.3" barrel.
Shooters and law enforcement typically choose the 11.5" barrel, as it has better overall performance, especially in the heavy (SOCOM) profile. Our LE customers tell us that they will only use Colt barrels in 10.3" to 14.5" lengths. Colt truly does dominate that market, while other barrel companies own the long-range and sniper market.
