Caliber: 6.5 Grendel - This barrel is chambered in 6.5 Grendel, a precision cartridge developed for the AR-15 platform, designed with superior long-range ballistics, and is a great middle-ground between 5.56 NATO and .308 Win in long-range performance.
Material: BSF Barrels are made out of high-quality precision machined 416R Stainless Steel with a jacketed carbon fiber sleeve to increase rigidity and save weight.
Finish: The 416R Stainless Steel is polished and buffed, including a carbon fiber jacket around the barrel to add to a slightly contrasting grey & silver color scheme.
Thread Pitch: 5/8x24 - 5/8x24 Threads are commonly found on barrels chambered in .30 Cal and up. Usually .308 Win, .300BLK, 6.5 Grendel, 6.5 Creedmoor, and 7.62x39. Muzzle Devices such as flash hiders, blast cans, and compensators will work with this barrel.
Fluted: BSF Barrels are button fluted in the jacketed carbon fiber around the stainless barrel, allowing for adequate thermal vents and an increased reduction in weight.
5R Rifling: 5R Rifling is a different manufacturing method to standard barrel rifling, where the rifled grooves are smoothed to allow more engagement with different parts of the projectile, this decreases drag in the barrel during acceleration and allows for a more stable projectile out to longer ranges.
Barrel Extension Finish: BSF Barrels come with identical 416R Stainless Steel Barrel Extensions to ensure proper and reliable feeding, along with proper and solid engagement with your bolt carriers locking lugs.
