gunsmith recommendation needed

I need this done to a barrel with existing threads without shortening the barrel. The current threads are 5/8-24 (30 cal barrel) with no "relief cut" as pictured in detail E.  I need the relief cut added to the area behind the existing threads. Appreciate any recommendations as to a good smith, preferably on the west side or within a couple hours of Seattle.

Why do you need the relief cut? Does the muzzle device not seat against the shoulder as is?

[Sneaky]

does not seat evenly. Its one of those situations where it would probably be fine but something you always would wonder about. this may be my only suppressor and I don't want to ruin it with a possible mis-alignment. I sent photos to thunderbeast who said they could fix it, but not sure if they could get it done before the new laws pass and/or if the new laws will effect that sort of transaction. Would rather go local

Pretty sure Benchmark Barrels could do that . If you want to drive The Range in Yakima can do it .

I'd definitely start with Bechmark.

One option if you want to cut the relief yourself with hand tools at home.... Put some masking tape or something similar on the shoulder (blue). Then use a hand file (red) to remove the threads and create the thread relief. Twist the barrel slowly as you make strokes with the file to prevent making flat spots.

Do other muzzle devices have the same problem on that barrel? If it is not seating properly, you may have more than a problem with the runout on the shoulder and more than a relief cut may be needed. Is it stopping short of the shoulder?

The only two gunsmiths I would have used had left Washington state.  :'(

When I went to install the brake at home I noticed a bit of a daylight behind the peel washer that gave me pause. I got in contact with thunderbeast and confirmed after swapping photos with their tech guy that the barrels setup lacked the necessary relief cut behind the threads. From what I gather its likely fine the way it is but I definitely don't want to find out the hard way after the investment it takes to get a suppressor. If its as simple as paying someone with skills and equipment to craft it to exact thunderbeast specifications thats well worth it to me.

On a side note, shout out to dreadi for the awesome suppressor and second to none customer service! Anyone in the market for a suppressor should order through him. He was willing and able to get me the exact suppressor I wanted when several big box stores told me they were too busy.

you're right not to want to use it as is.

I forgot about Liam Riley. He does gunsmith work. I have never used him but I spoke to a few people that he has done work for and they are all more than impressed with his work.

As someone who has spent a few years at a lathe, I can tell you this; if the shoulder isn't square to the axis of the bore, the threads at the muzzle aren't either.

Here's another tip for anyone screwing a suppressor onto a barrel it hasn't been on before (This applies to all suppressors and all barrels).

1. Screw the suppressor on snug.
2. Take the bolt out of your rifle.
3. Look down the barrel from the rear end.
4. Rotate the barrel and pay close attention to how much of the suppressor baffles you can see through the barrel.  As you rotate the barrel, you should be able to see the same "amount" of baffles all the way around. This indicates good alignment.  If you see more of the baffles on one side than the other, proceed with extreme caution and you probably want to consult with someone you trust as an expert in this field.

--Note: In some situations you won't be able to see any baffles.  This is usually ok.  An example of this would likely be screwing a .308 can on a .223. The baffles will have so much clearance from the bore of your .223 barrel that you won't be able to see them.  However using a .223 can on a .223, or a .308 can on a .308, you should be able to see some of the baffles. Barrel length and inner diameter tolerance of the suppressor baffles will also affect how much you can see.  The key point though, is ensuring you see the same amount of baffle on every side as you rotate the barrel while you are looking through it.
