Gauntlet Arms "Cucha" AR-15 20" .350 Legend, Carbine Gas, HBar, 1-16T, Phosphate Barrel
General Barrel Info: The "Cucha" 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 This Barrel: The Barrel is made by Gauntlet Arms it is 20" long, and is machined from 4150 Chrome Moly Vanadium and finished in a manganese phosphate appearance. Chambered for .350 Legend, using a H-Bar profile design, this barrel will fit your next AR-15 build perfectly.
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.
