Barrel pinning recommendation

[FUNCTIONAL]

Need to get a device pinned and welded. Who do you guys recommend for it?

Hoping they can pin and weld it in a way that I don't have to destroy the brake completely if I ever need to remove it in the future.

 

[oldrifleman]

While it is possible to remove the muzzle device, there will be significant damage to it, otherwise the feds may rule it was not truly pinned and welded.

 

[BCP]

ADCO is suggested quite a bit on here but any decent smith should be able to pin and weld it for you.

John Thomas at Retro Arms. He removed a pinned MD and mounted and pinned a new one. Mailed to him on a Monday and I had it back in hand by Friday. He has also mounted an A2 front sight for me. Excellent work and very fast.

don't have to destroy the brake

If you carefully drill the weld (or use a small end mill) it won't ruin it.

 

[Aftermath]

The weld is RARELY all the way to the barrel threads. It’s just a little cap weld to make it difficult to remove the pin that is sitting into a hole drilled just barely deeper than the threads to prevent rotation. As @smoothy8500 posted above, careful drilling of the weld will allow the pin to be free and removed. It’s not even necessary to have a machinist or gunsmith do it. This is how I have the same brake on my third barrel. I also pin and TIG myself…and I don’t own a lathe or milling machine.

That's what I'm looking for. Just mill off the "cap" and let the pin fall out. Looks like D. WILSON does that. The go to adco looks a bit more permanent.

D Wilson did my lmt like this. It looks great.

JT is good. Had him pin a fsb for me and some other mods to it for an xm16e1 clone.

D Wilson or ADCO if you're planning on shipping it out to get done. Whatever you do, if you go with a local guy, make sure he knows what he's doing and uses TIG. If not, this is what might happen:

@Desert_Racer yikes. The only local guy I trust is currently not taking work so that's why I need to send this out. I do all my own work normally but I don't own a Tig or mig welder and don't see spending $$$ when I just need to do this pin.

I got one better

If your muzzle device needs to be timed, and you don't want to use a crush washer, do that yourself before sending the barrel in. Same thing if you're concerned about over torqueing. It might sound like a simple job, but specify your expectations with the gunsmith before having the work done. Some places, like ADCO, will not time a muzzle device using shims prior to pinning, and other places may charge extra for shimming. There are one or two other considerations if it's a suppressor mount.

You don’t have to pin and weld to be legal. Silver soldering is 100% accepted as a permanent and is reversible

 

[cas6969]

^ With the right stuff, but how do you know?

 

[oldrifleman]

That’s a risk I won’t take.

 

[cas6969]

Of course I paid to have a weld job that wasn't legal either, so I guess unless you do it yourself you'll never really know.

 

[FUNCTIONAL]

I'm capable of brazing but I have no intention of doing that. At least if I have to destroy something it's only a brake with the pin/weld. In not sure if you could ever clean up the threads enough to be workable after a silver solder.

It's a kac NT4 mount. Nothing super fancy but will have a suppressor on it.

I turned a spacer on my lathe to time correct. D. Wilson offers to time it.

 

[Jsp556]

D Wilson does good work.

 

[oldrifleman]

Would trust that he would do a spectacular job.

Bottom of page 5 under the shotgun pic talks about permanent fixtures

 

[cas6969]

Not how do you know what's the right stuff, how do you know they used the right stuff.

But like I said, I know from first hand experience that the same goes for a pin and weld job. (Having paid one of the places above to do one, only to find out years later when I removed it that their pin not only didn't enter the barrel, it didn't even completely pass through the comp)

If it was mentioned here say who. I don't want to be sending my barrel to someone that's going to catch me a charge later.

Trying not to beat the long dead horse.... ADCO.

 

[912173]

I decided to do everything that I could by myself and then have a local experienced welder tig weld the pin.

I was able to personally make sure of:
Timing/orientation/correct shimming
Torque
Checked alignment with suppressor
Matching 17-4 ss pin material to device
Pin length/depth

Now I just need to arrange to have my welder friend tig weld it. No shipping and no wondering how somebody else did everything.
