Looking for a reputable shop to thread barrel and add a shoulder

[MuleyFever]

Who has had this done and who did the work?

What do you mean by add a shoulder?

Shaen rifles does a lot of this for wkrs. @thinhorn_AK has a bunch of pics posted.

I have 2 at pva right now, the adapters they're setting me up with are no where near as visually appealing as shaens work, but they're driving distance for me vice across the country.

I would check with longrifles Inc. Chad does excellent work, and fast turnaround times.

 

[thinhorn_AK]

Shaen rifles does top notch work. I should probably just make a whole thread about is since I’ve had 12 people PM me for details.

 

[WeiserBucks]

I would also recommend LRI, but I haven't had them add a shoulder to anything.

ADCO Firearms did my Tikka sporter barrel. All I can say is it shoots very accurately

 

[Antares]

Kampfeld Custom did this one.

How do they attach that piece to the muzzle?

The muzzle is threaded long enough to screw on the new “shoulder” piece which is then machined to fit seamlessly to the barrel contour then it is Loctite’d. At least that’s the way I do it.

Shaen just barreled and bedded a rifle for me. His work is top tier. One of the few that gets work done in a timely fashion.

That makes sense.

Kampfeld is a stud. He will get you 100%

It's just a blended adapter. Its not doing anything any other adapter won't. Except looking way better.

Not according to TBAC. The thread on adapters like 1/2x28 to 5/8x24 don’t solve the issue of the lack of material by the shoulder. Something like is being shown in this thread do solve that issue.

If you know something TBAC dosent know we’d love to see/hear it.

 

[thinhorn_AK]

So you mean to tell me something like this doesn't have just as much shoulder as you're fantasy pants little blended do hickey?

Fancy pants? You seem to be really emotional about certain topics but yes. According to TBAC, those adapters don’t solve the problem of a lack of material between the threads and the base of the barrel.

I’d recommend you contact TBAC though as they are experts and I’m just a guy on the internet.

The issue is not just the shoulder but the material between the bore and the threads.

From the LRI site - "Our experience has shown that a thin wall muzzle has the potential to "bell mouth" over time. When a crown bell mouths, the accuracy of the rifle suffers. You as the user may be compelled to think the barrel "let go" due to throat erosion when it's actually because the muzzle was threaded with too thin of a wall thickness."

So the way the added shoulder works is it threads the muzzle to the largest thread possible and that leaves the wall thickness as thick as possible.

Do whatever you want on your guns. Merry Christmas!!!

Just because it supposedly has a little more meat and is blended doesn't mean its not a threaded adapter.
Thats all it is, he did not weld on a section of larger barrel or any such nonsense.
It has threads in the inside and outside.
Its a threaded adapter.

If I understand it correctly it is literally not a thread adapter. It is not converting one thread pitch to another. It is threading the muzzle to the max thread pitch to keep wall thickness and then adding a collar.

That is correct, the threading used to attach the adapter is non standard.

It does not appear to have rifling in the end. That tells me its not part of the original barrel.

Its OK that you dont understand how it works.

Maybe thinhorn can post a pic of the end so you can see its not an adapter.
