Barrel Length Choice Verification

[TX_Mike D.]

I’m going to call Peter tomorrow, but Paul seems to be able to thread everything to 5/8x24 (the threading the suppressor I’m buying comes with). Peter said in his email that all the thinner barrels will have to be threaded to 1/2x28. I’d like to keep everything with compatible threading. Am I being too OCD about this?

Just get a 1/2-28 to 5/8-24 adapter, pretty simple.

I guess my question is why? By the time I’ve bought a few of those I’ve probably spent about as much as the shipping to get the thread pitch needed for the suppressor out of its box.

IIRC, the way Paul explained it to me, is that the diameter of the barrel (thin sporter) at the place I wanted it cut, just wouldn't allow for both a proper shoulder and the 5/8 threads, and that the solution was to do the 1/2 threads, and permanently mount the adapter/shoulder on top of that. The job he did for me turned out exquisite - beautiful, smooth, very competently done.

Here's a photo of the adapter/shoulder, and the thread protector he also fabricated for it, from scratch. Barrel and protector are also coated with KG Gun Kote, which is quite a bit better for durability/scratch resistance than cerakote:

This was my understanding from the little bit of research on it. Basically permanently attaching the adapter and machining it to match the barrel. There are some pretty slick videos of it being done.

No experience with the smith you’re using but I’ve had a few barrels cut and threaded. All your tikkas should be able to be threaded 5/8x24. Pic is of a 6.5cm t3x lite I had cut at 18” and threaded by Kampfeld. Expecting to get my 18” 308 barrel back from him any day. The Kimber barrels are pretty thin, you might have to go 1/2x28 on that. I hunted with a 300wsm barrel threaded at 1/2x28 for a few years, no issues, I still have it in case I go somewhere with a 30 cal minimum.
