Bear Creek BC-10/AR-10/LR-308 20" 6.5 Creedmoor Heavy Profile,
Rifle Gas 1:8T, Parkerized Barrel
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 as 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.
About This Barrel: This 20-inch heavy barrel from Bear Creek Arsenal is crafted from 4150 CMV with a parkerized finish to make it durable, strong, and corrosion resistant. It is chambered for 6.5 Creedmoor with a classic 1:8 twist rate. It is precision rifled and carefully inspected to ensure it has high accuracy.
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.
Barrel Classification: Rifle
Length: This Barrel is designated as a rifle barrel with an overall 20" length.
Caliber: 6.5 Creedmoor - This barrel is chambered in 6.5 Creedmoor, an intermediate version of .308 Winchester, with a higher muzzle velocity and ballistic performance at longer ranges. 6.5 Creedmoor was developed for the LR-308 / AR-10 and is the preferred caliber of many long-range enthusiasts due to its consistent performance at extreme ranges.
