General Barrel Info: The barrel on an LR-308 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. LR-308 Barrels come in four different specifications for gas systems, Pistol, Carbine, Mid-Length, and Rifle. LR-308 Barrels vary between profiles as well from Government, to Heavy, and Slim. Thanks to the modularity of LR-308, you can choose different calibers starting with the barrel, each with its specific twist rates. Choosing your barrel for your next LR-308 build has never been easier.
