From the manufacturer
Noveske Lo-Pro Gas Block 300 AAC Blackout Barrel 10.5in Shorty Pistol Length Stainless .750 Gas Block Headspaced Bolt 0. 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. Noveske Rifleworks LLC will not be responsible for damage or injury under ANY circumstances. Consult you suppressor manufacturer to determine if your suppressor is suitable for this application.
