Anyone know who is doing ghost threading? I have a couple 22lr barrels that I need threaded.I thought gemtech used to do this but I can not find it on their site.

What is a ghost thread?

I'm guessing it's threading that passed away but has yet to move on?

I viewed it and I felt like an ass b/c I didn't knwo what 'ghost threading' was.

I went out in the shop and asked to of our machinist and they both gave me this:

So, I couldn't offer you up an answer

it is where a grove is machined into the muzzle end of the barrel ....the inside of the grove is then threaded.....making the host weapon for a can appear to be unaltered. There was a company offering this at one point in time but I dont remember which companu it was.
possibly called phantom threading as well.

Like this? Or are you talking about having internal female threads put into the muzzle and the can would screw "into" the barrel?
I can't imagine the latter to be the case due to a threaded muzzle crown causing poor accuracy.

Anyways, I had that pistol done at Tornado Technologies. Great guy, Awesome work.
It's seamless when my pistol is clean. 22lr tends to get dirty... And I tend to NEVER clean it

I'm trying to picture what you are saying.

Something like back boring the muzzle end, then doing internal threads...like a shotgun choke? Then use a threaded adapter for muzzle to can?

yes.

The point is that there is no thread protector to loose or misplace. and just by looking at the gun you would never know anything was done to it. you have to look at the muzzle to see the part thats been machined. Just a little something different.
Someone on another board said that it was called phantom threading but they didnt mention who did it.

I believe John Noveske used to do it.

You may want to try tornado technologies, they are over on silencer talk alot. Or just google his name I believe I saw something he did over there that was like that.

Another option would be Mark McWillis at TROS. Here's a barrel extension adapter he made for me. No reason he wouldn't just thread the barrel (instead of the adapter) internally. You would need an adapter between the can and an internally threaded barrel.

FWIW, though, from experience I won't use internal threading. Because when you shoot without the can/adapter installed, the internal threads crud up, and there also is a buildup against the rear shoulder of the internal threads. After awhile, it's difficult to keep the can installed tightly and still borecentric (i.e., baffle-strike-free).

So if you go with "ghost" threading, be fanatic about keeping those threads clean!
