Gauntlet Arms "Dire" AR-15 16" 12.7x42, Carbine gas, Hbar, 1-20T Parkerized 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.

About the Profile: H-Bar - A heavy barrel adds a lot of weight to the rifle but a rifle thus equipped is more accurate than a rifle with a normal barrel because a heavy barrel heats up much more slowly than a normal barrel. With more material added, a heavy barrel by design is structurally stronger and more accurate.
