Faxon Firearms AR-15 16" Gunner, 5.56 NATO,
Mid-Length, .625 Gas, 4150 QPQ, 1-8T Barrel
General Barrel Info: The barrel on an AR-15 originally operates under a 'gas impingement' system, by tapping gas off of the barrel and cycling it back through the gas system to assist the bolt carrier in unlocking and extracting the spent cartridge. AR-15 Barrels come in four different specifications for gas systems, Pistol, Carbine, Mid-Length, and Rifle. AR-15 Barrels vary between profiles as well from Government, to Heavy, and Slim. Thanks to the modularity of AR-15, you can choose different calibers starting with the barrel, each with its specific twist rates. Choosing your barrel for your next AR-15 build has never been easier.

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.
