ELD Performance 4.5'' 9mm AR-15 Barrel, 1:10 Nitride , 1/2x36 Thread

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.
