Is there a standard thread pitch for suppressors? I have never had one, but want a .458 and want to get the barrel already threaded. What pitch should I get it done in?

5/8-24 for .308-.45 diameter barrel. There are not many ready made 458 suppresors available. Tha being said it will more than likely be custom, meaning you can thread it to what ever you want. 5/8-24 will give you the most options, K3X, Vortex etc.

My .458 SOCOM's barrel is threaded 5/8" X 24.

Being a bit anal about accuracy, do you know of any testing that has been done - specifically on the .458 - with before and after muzzle threading? I know from experience on .22's rifles and revolvers that it can possibly have a very detrimental affect.

Thanks

I would go 3/4 x 16 or something similar.
This gives a much stronger mount without the possibility of distorting the bore due to tightening of the suppressor.

but if I change the pitch to something like that, everything/anything I ever wanted to add such as a supressor or compensator would have to be a custom made piece, no?

If your worried about the 5/8-24 on 458's go look at the guns over at 458socom forums. Most guns are threaded with either a FS/MB in this same pitch. Mine is threaded and it will shoot a 1 moa 5 shot group on my good days. Im sure you could get it too thin and mess up the accuracy but 5/8 24 seems to work.

You are correct about the "non-standard" threading. You would have to have custom work done, but if your really worried about the accuracy it might make sense. But if you are that worried then dont thread it.

If you get a suppresor, will it go on any other gun? It might actually be a good idea to have it threaded differently if it will be a purpose built suppresor.
