Firstly, moderators, if you think that this thread should have been started elsewhere, feel free to move it. I'm new here and not familiar with the subtleties of this forum.
Secondly, my reason for posting. I am currently in possession of a 22" Wolfe medium-standard weight 5R barrel. It was my intention to have it cut down to 20" and rethreaded. I initially believed that I could get away with having 5/8-24 threads put on it, thereby giving it all the flash hider / compensator options of the AR-10. Unfortunately, I discovered that M14 barrels are quite thin. This particular barrel measures at 0.609" at the 20" mark, too small for 5/8-20 threads. I believe the largest practical thread size for this barrel M15-1, a thread size that there is at least 1 muzzle device option for that I've found. But, the small barrel diameter brings about another question. What part of the barrel do AR-10 type flash hiders and muzzle brakes butt up against when tightened? There are only 2 spots where this can occur, between the bore and the threads at the muzzle, and between the outer surface and the threads behind the muzzle. The second option would not be possible if I used M15-1 threads as there would only be a roughly 0.009" surface for the muzzle device to tighten against. Unless I'm mistaken, most AR-10 type muzzle devices butt up against this part of the barrel, rather than the muzzle. I would like to shorten the barrel. 18.5" seems a bit short to me, and I don't believe Wolfe offers a 5R rifled 18.5 inch barrel. A 5R barrel is desirable since it should be easier to clean. Likewise, 22" seems a bit long, and I would prefer to have the muzzle device attached directly to the barrel, rather than attached to an adaptor that is then attached to the barrel. My intent is to eventually attach a QD suppressor to the rifle this barrel will go on, so my muzzle device options are a bit limited. This is also why I'm concerned with barrel length. I have no intentions of using this rifle as a vaulting pole. If any of you folks have attached a suppressor and/or a muzzle device to a cut-down M14 barrel, I would love to learn about what setup you decided to run with and what other options you discovered during your build.
