Can anyone in W WA thread the muzzle of a PRESS-FIT barrel - Mauser M12???

[slm9s]

I have a Mauser M12 308 that I love, but I'm converting my rifles to threaded barrels for use with suppressors.  The Mauser M12 has a Press-fit barrel - not threaded into the action.

I'm in Tacoma, but can travel.

Thanks in advance.

What makes the threading of these any different than any other barreled action?

SLM9S,


Benchmark in Arlington did one for me. I dropped off the whole barreled action minus the stock and bolt. They cut, threaded, and re-crowned it with the action still attached I believe. It was a R700 SA action, but I could not see evidence of them needing to remove the barrel from the action when I picked it up.  Turned out nice. They did a terrific job.

Normally, you 'unscrew' the barrel from the action so you can spin just the barrel in the lathe.  For these Mauser M12's, they are not screwed into the action, they are 'pressed' into the action.  So the barrel can not be removed and the barreled action will need to be together while the muzzle is threaded.  That's why I'm reaching out to see if anyone has done something like this before.

Maybe just give a couple gunsmith shops a call and ask them direct??

Trying to understand what you're after. Are you saying you want to have your M12 threaded for suppressors? If so, you really don't need to remove the action. The smith will insert the barrel assembly through the head stock left to right giving them ample length to cut threads and recrown.

I've threaded a few barrels with receivers attached. I actually prefer to not have to remove the barrel from the action.  It can be done.

1st choice if barrel is long enough, slide the barrel through the headstock and center it using a dial indicator and the 4 way chuck on the muzzle end and a spider on the breech end.  I think my lathe can do this for 24" or longer barrels. Some lathes have shorter headstocks and can use this method for shorter barrels.

2nd choice, if barrel isn't long enough, creatively and carefully clamp 4 jaw chuck onto receiver. Use stead rest and/or live center to support the muzzle end for threading.  Also use dial indicator to center it.

3rd choice, if possible, press barrel out of receiver, thread it, and then press it back in.

Definitely possible, just depends on the setup used and if the barrel is long enough to poke through the headstock. I think I've done them down to 22" or maybe even shorter if the front of the action will fit into the headstock a little bit. Just can't spin it too fast with action attached. I don't remove the barrel unless I have too.

I'm pretty sure these had a 20" barrel

Thanks for everyone's responses

I have a guy in Oregon that threads my barrels with the barrel still attached to the action. He just runs it through the through hole in his lathe. As others have said there is no reason to unthread the barrel from the action.

A gentleman local to me was able to get this done.  Thanks everyone.
