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.

Chambered in 300 AAC Blackout, this stainless steel beauty features a 1:7 twist rate, extended feed ramps, and 5/8x24 threads. It comes with a Noveske low profile gas block, bead blasted to match the barrel's finish, the gas tube, and a Noveske bolt that has been headspaced to this barrel for guaranteed accuracy and reliability.

Installation of the gas block taper pins and gas block is required to complete the assembly process.

Noveske’s 300 AAC BLACKOUT is designed to run optimally firing both subsonic suppressed and supersonic unsuppressed. This barrel is tuned to lock back on the last round using subsonic 220 and 208 grain ammunition with a sound suppressor. The firearm may not lock back with subsonic 220 and 208 grain ammunition without a sound suppressor. Also, the subsonic 300 BLK ammunition is more susceptible to a malfunction due to carbon fouling and adverse conditions than supersonic ammunition. The barrel is tuned to operate correctly with the back pressure provided by the AAC 762-SDN-6 using an H2 buffer, or a Surefire 762K suppressor and an H buffer. In the development of this barrel, we found evidence that the suppressor may require a symmetrical baffle stack as found in the AAC Cyclone K, 762-SDN6, and Surefire 762K suppressor. Suppressors which cause off axis turbulence, such as those with K type baffles, may cause baffle strikes and/or point of impact shift, and may damage your suppressor. Consult you suppressor manufacturer to determine if your suppressor is suitable for this application.
