Most sporter profiles, and those of the like do not provide enough material to produce a proper shoulder. In some instances you may be forced to use a smaller thread and/or employ an adapter. What if you had enough of an OD to produce the proper thread, but no shoulder?
What are your thoughts? Shouldering muzzle devices on the face of the barrel vs an actual, machined, shoulder on the OD of the barrel. Is it strictly situation dependent? Do you feel it is best left to particular calibers, pressures, etc. I wouldn't do it with a brake, flash suppressor, noise suppressor, Nielsen device, etc.. |

contact a PROPER and COMPETENT gunsmith... not some local lathe jockey... I am a competent, hobby, machinist with plenty of design and fabrication experience. My query was more of a topic for discussion than a particular suggestion. It seems this section has become a bit stale in the expertise discussions. A lot of the topics are rehashes and/or belong in the general section. I was trying to introduce a fresh talking point for those versed in the particulars. With suppressors becoming legal in more and more states, the question of which thread pitch to use is a popular one. It is more user friendly to get interchangeable, direct thread, muzzle devices in a common pitch, yet, not every barrel can support the options. |

Some of it is dependent on the suppresor. Some will register on the shoulder, the muzzle face, the threads or a combination thereof.
I have done plenty of smaller profile barrels, say .620 diameter in 9/16 x 24 TPI then used an adapter to get it to 5/8 x 24TPI. But you have to watch for stacking tolerances. There are other times I have sweated on a bushing and then turned and threaded the bushing. Quite a few of my customers only have one or two cans and prefer the QD approach. I think it is safe to default to what the suppressor manufacturer calls out regardless of the customers wishes. |

IE: using the 338 thread on all 30cal and less bores.. |

Having a barrel so thin that a proper shoulder couldn't be integrated, man in my feeble mind that introduces so many variables. Barrel vibe being what it is in thin barrels, and hanging a suppressor on the end of that thin a profile...man I would think the shots would be everywhere, especially indexing on the muzzle instead of the shoulder. I need another drink to ponder this one. |
