Noveske DDF Barrels

[kthomas]

I’ve had a discussion with a man that was primarily chopping scar barrels. For my heavy, he was strongly recommending to cut a 1/2 thread pitch as to add more shoulder for the muzzle device to sit on, making it a more robust suppressor host.

I never proceeded in this manner, but I think about that premise a bit.

That's the other school of thought.

School 1 is to have as big of threads as possible to prevent any "belling" of the muzzle. Some will go as large as 3/4" threads to mitigate this.

School 2 is to have smaller threads to allow for a larger shoulder for threaded devices. TacOps uses 9/16" threads for this reason.

I don't think there's really a right or wrong answer, it just depends on what your objectives are and what tradeoffs you are willing to make to accomplish them.

That’s because SCARs have no shoulder to speak of, especially the 17S.

Understood, and this was just one manner of addressing that.

I don’t have enough information to decide whether I mind the barrel diameter being pretty significantly reduced all the way out there, with another 7” of material that can easily be leveraged against a barricade. It certainly feels like a non-issue….

Muzzle devices that index on the muzzle face is a far better option than small OD threads.

Not familiar with muzzle “face”, synonymous with barrel shoulder?

No, the muzzle face. The muzzle face is cut concentric to the bore just like the shoulder. Companies like Griffin Armament make devices that with concentric shoulders, threads, and muzzle faces. Depending on how long the barrel threads are, you may need to turn back the muzzle device shoulder to make contact with the muzzle face. Modifying the muzzle device is a much better option than smaller OD threads on an already anemic barrel OD.

Sorry, I’m stupid. Muzzle face is the very front of the barrel then, the part that the device will index and the part that gets crowned? If so, I now understand your comment. The device may bottom out at the muzzle face before the shoulder is met by the device.

My DDF barrel caused me to trip while running a stage yesterday.

I mean I blame the barrel.
