General Barrel Info: BSF Barrels are premium, high-end sub-MOA barrels with the unique properties of incredible heat dissipation. With the carbon fiber stainless steel construction, the barrels are incredibly lightweight, with rifle-length gas system, these will make your AR-15 have an incredibly smooth & light recoil impulse, giving you the edge in competition. MMC Armory offers barrels from BSF in .223 Wylde, 6mm ARC, and 6.5 Grendel.
About This Barrel: The Premium BSF Carbon Fiber barrels were designed with accuracy and weight-reduction in mind. Completed with a polished fluted stainless steel and carbon fiber jacket to reduce weight and increase rigidity. Produced with 5R Rifling, 5R Rifling improves the engagement of the projectile to the twist of the barrel for a more stable flight over longer distances. BSF Barrels will be a premium addition to your next rifle build.
About the Profile: BSF Barrels before the jacketed carbon fiber addition, use a pencil profile, and after the carbon fiber jacket is applied to the finish of the rifle, after the manufacturing process is finished, BSF Barrels take on a balanced medium profile barrel, with incredible lightweight properties.

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.

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.
