General Barrel Info: The Barrel on an AR-15 pistol operates through a 'gas impingement' system, where gas is tapped from off from the barrel and cycle back through a connected gas system, to help the bolt carrier in unlocking, and extracting a spent cartridge. Pistol length AR-15 barrels come in two gas lengths, Pistol, Carbine, & Mid-Length. AR-15 Pistol barrels can be chambered in a variety of different calibers, spanning from rifle to pistol cartridges. Thanks to the modularity of the AR-15 platform, your next pistol will be incredibly easy.

About the Profile: Medium - Medium Profile barrels are designed to have an even weight distributed from the beginning to the end of the barrel, this results in a rather tubular looking appearance but with identical rigidity and properties to a government profile barrel.

Length: This Barrel is designated as a pistol length barrel with an overall length of 4.5".
Caliber: .45ACP - This barrel is chambered for .45ACP, a low velocity, high mass, hard hitting pistol cartridge, most popular with 1911, adapted for the AR-15 Platform.
