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. 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.

Quite sure Noveske makes great barrels with longevity and quality but the issue with gas block has been going on for quite sometime now with no remedy. Gas block issues are prevalent among reviewers. Other said take your time, put it on leather, paper blah blah but upon inspection, the issue is that —> The groove for the pinned gas block is not perpendicular to the gas port hole axis. The groove for the pin is canted at 3-5 degree therefore as you drive the pin (no matter how much careful you are or how much time you spend driving it), the pin will only go its natural course of path. The end result is a Canted Gas Block with the tube slightly pushed on one side of the receiver tube hole. Judging by its finished install, it "Probably" not going to affect its performance since the gas port hole-tube is still aligned and the the bolt only a minute almost nil binding. You may say, well, its working, yeah sure but for that price, you expect impeccable craftsmanship. Heck I could have gotten other brand, say Ballistic Advantage!
