Self barrel threading

[1990dtgl98]

Anyone self thread their own barrels? I have 2 savage 223 varmint guns and want to get them threaded for the suppressor I have on order. However, seems at the cost (about 80-100 dollars a barrel), I could buy something like this:

..and do it myself. Seems pretty straightforward. I have a ton of mechanical experience and equipment (auto repair and heavy equipment). It seems for about 100 bucks I could have the cutter and the 1/2-28 die and save money. Hell I have 2 tap die kits, one of them might have a 1/2-28.

I was just curious if they were effective? I was also curious if the pilot rotates (and thus if there would be any issues with affecting the rifling using the pilot to maintain a concentric cut with the bore?

Anyone use them? Anyone have any opinions?

Thanks,

David

I've done it to several rifles. It isn't difficult or even very time consuming. The issue you will have is that a commercial .223 barrel is going to need to be turned down to be the right diameter for standard .223 threads. Paying to have it turned down and threaded isn't going to be much more than just having it turned down.

Unless you can absolutely insure that when using that device that the threads are PERFECTLY concentric with the bore, then don't do it. The slightest deviation can/will cause baffle and/or end cap strikes, destroying the suppressor. Gunsmiths who do this type of work are worth what you pay. They have the right equipment and know how to set everything so that the threads are concentric with the bore which means the bullet will exit the bore and the suppressor without hitting anything.

Those tools are fine for DIY threading of a barrel for a flash hider or a muzzle brake. The tolerances for a FH or MB are a LOT greater than those required for a suppressor (the suppressor needs tight tolerances to work correctly).

$80 to $100 to have the barrel done correctly is not a bad price (might save you upwards to $1000+ by not having your suppressor destroyed on the first shot).

That tool couldn’t be more wrong for turning a diameter. It’s basically a hole saw, meant for cutting holes in thick material. How they even sell that as a barrel turning tool boggles my mind. I’m glad they at least include a disclosure that “annular cutter does not cut at exactly .500” because rotobroaches rarely cut a nice hole to the OUTSIDE diameter they are supposed to, which is what they are normally sold for.

Also there are 2 types of dies. Dies meant for chasing existing threads(to clean off burrs or damage) and then dies for cutting threads, which is what you will need. Even with the proper die it’s difficult to make concentric threads.

So in conclusion, find a gunsmith.

One immediate concern comes to mind. The pilot is rotating inside the last bit of rifling at the muzzle. That in itself is a big not in my gun.

They designed it to have the pilot not rotate, the tool rotates on the pilot. But none the less still wouldn’t use it.
