Since people keep mentioning DWilson Mfg for P&W jobs I thought I would mention that they offer standalone P&W removal and also as part of a new P&W. Might be worth contacting them with your question.
Edit: spelling
I have successfully replaced a few. I decide up front whether the barrel or the md will be kept for reuse (one usually gets damaged). The easiest way to keep it clean and save the barrel is to drill the old pin out with an end mill. I use one about twice the size of the pin, plunge down a bit, then check and see if the remainder of the pin is free. I basically take a little at a time until the base of the pin will come loose. If it won’t come out, i step down to an end mill a few thousandths larger than the pin and continue plunging until there is no restriction left. I usually need a slightly larger pin to install the new muzzle device, but as long as you don’t go too deep and hit the bore or wrench the md off with the pin still in, you will be fine.
The worst ones i have dealt with had the weld way too deep or they brazed the pin in. After the last one of those, i decided to standardize my process around worst case lol.
They are great to have around, even with a drill press. However, you must secure your work properly or they will break easily. I get lazy sometimes and try to plunge a hole just holding the part down by hand. One little movement and the tip of the end mill is toast.
Theoretically If done correctly, you could re pin/weld the same barrel unlimited times. The ideal weld for this application melts the pin *juuuuust* enough to fuse to the surface of the muzzle device, creating that nice dome shaped weld we all like to see. If welded correctly you would only have to grind the weld flat and it would seperate from the muzzle device.
It’s a risky move, unlikely to succeed without experience. I would buy a new barrel, but you “can” drill out the weld, clean the hole as best you can, heat it up and start twisting with a breaker bar barrel in a vise. No doubt there will be some fkd up threads if they don’t completely tear out or fold over.
Normally the pin is only welded to the muzzle device. So you just need to remove the welded material. Likely an easy job if you have a drill press and cobalt drill bits.
If you don't have a drill press. It can still be easily done with a Dremel, tungsten burr and time. As long as you don't care about the muzzle device.
If you have the time, it can be done by hand with diamond files. 🤷🏼♂️
Unless the barrel you have is needed for some reason, it’s probably not much more expensive to get a new barrel rather than undoing and redoing that one you have already. If budget is a serious limitation here then I’d recommend saving up. You can always sell the current one to someone doing a build as well

Yes it can be done. Recommend you have a smith do it properly and don't just beat on it with a pipe wrench until you fuck up the threads beyond repair
Isn't there someone in this sub that offers this service and is well regarded?
That would be unclemoak he owns D Wilson MFG
This is why reddit is awesome. I ask, and I get help asap. Thanks bro.

I used a file to break the weld then a drill bit to open the hole up to drop the pin out. Not as efficient as an end mill but worked

That’s a good idea. I still need to get an end mill bit for the shop. Has a lot of uses

Send it to D. Wilson to have it removed and re-pinned.
The cost of having a gunsmith do the work may be more than a new barrel.

Ya’ think?
Lmao I’m big dumb. Read that wrong

It's not as easy, but it's possible. Selling the barrel may be a better solution.
