Suppressor on a sporter barrel?

[Jpsmith1]

As I'm researching and learning about suppressors, I'm being told that putting a direct thread suppressor on a sporter weight barrel is kind of a no-no.

Something about a shoulder behind it for alignment. This makes sense plus the steel being thin and not allowing much metal for strength.

Is this true?

I just measured 0.667" with cheapie calipers so I wouldn't trust it to the thousandth but it's close enough to chat about.

Can this barrel be threaded? 7mm Rem Mag 23" barrel. Not a ton of taper. Even at 16" the barrel only measures 0.690

When it gets threaded, the Smith can machine a little further and put a flared shoulder adapter on a sporter barrel. This will give you something to snug up against. No reason not to run a suppressor.

The ADCO website has a good example photo.

I’ve had zero issues threading skinny barrels (Kimber Montanas, mostly) to 1/2-28” and using a direct thread mount. I’d certainly prefer a flared shoulder for more contact with the mount but it just hasn’t been a problem at all yet.

The right smith can put an adapter on it.

The wrong smith can mess it all up.

Your diameter is barely more than 5/8 so 1/2 28 threads is what you’ll get. Not a problem with a 1/2 28 direct thread can or a good 5/8 24 thread adapter for a 5/8 24 can. My guy will thread 1/2 down to .600. My 308 Montana was just a hair over that at 18” as I recall. Hasn’t been an issue.

Good rule of thumb is to have .675" to work with so you can thread 5/8" and have a total of 0.050" for a shoulder. Sounds like you could shorten perhaps to 21" or 20" (I didn't do the math) and have it threaded 5/8 or you could have an adapter added. Works either way and I'd wo whatever was simplest and suited me best and wouldn't lose sleep over it.

It was still muzzle diameter at like 20"

I'm calling a Smith tomorrow to talk about it

Just got mine back from Kampfeld. Had it cut down, adapter installed and cerakoted. Turned out great.
