KAK Industries AR-15 4" 9mm QPQ Nitride Fat 1-10T Barrel
General Barrel Info: The barrel on a 9mm AR-15 barrel operates under 'direct blowback' there is no gas system directly connected to a 9mm AR-15 barrel for the system to cycle. By design 9mm AR-15 barrels are affordable and come in many sizes, rifle, and pistol. This includes many of the familiar barrel profiles found on standard/common AR-15 platforms. Building an AR-15 chambered in 9mm is a great choice for training, or for your next Pistol Caliber Carbine build.
About This Barrel: The Barrel is made by KAK Industries it is 4" long, and is machined from 4150 CrMoV and finished in a Nitride appearance. Chambered for 9mm Luger, using a Fat design, this barrel will be a perfect choice for your next AR-15 PCC.

Caliber: 9mm - This barrel is chambered in 9mm, perfect for light recoiling pistol caliber carbines or rifles. 9mm is the most popular pistol cartridge in North America.
Material: 4150 CrMoV - Chrome-Moly Vanadium, or simply "CMV", is the official mil-spec gun steel developed by Colt Firearms for the military-issued M16 and M4. It contains the same elements as 4150 steel. It also contains Vanadium. Vanadium significantly increases the strength, hardness, and high-temperature stability of the steel.
