The National Firearms Act regulates the configurations of some firearms assembled with barrels under 16” long. Know the NFA laws in your state before purchasing this item.

The KAK Industries Value-Line 10.5” 300 BLK barrel has proven so popular, they have decided to make it a regular item. Give your AR-15 the extra punch of 300 BLK today! This barrel is built from durable 41V50 chrome moly vanadium steel and a Melonite finish for long-lasting corrosion resistance. It has a 1:8 twist rate to stabilize the both subsonic and supersonic loadings so you will remain accurate throughout the effective range of the cartridge. The pistol length gas system allows for reliable function even with subsonic ammunition as more gas hits the carrier at a faster rate to ensure that the bcg is cycled fully. With a .750" gas seat diameter you will be able to choose from a wide variety of gas blocks from adjustable to standard, and clamp on or set screw style. Adding to the modularity is the 5/8x24 thread pitch so you can attach most muzzle brakes, flash hiders, compensators, or any other muzzle devices.
