oss suppressor threads

[Dave Zander]

There is a left handed o.d. thread on the muzzle break adapter that the can screws onto. The major thread diameter measures 1.147". Does anyone have the complete thread spec, ie. pitch, included thread angle, minor diameter.

Go to the Advanced Armament Corp website, they have all of them listed, I think.

AAC only shows the barrel-to-adapter threads. The threads I think Dave is referring to are the ones for adapter-to-suppressor (correct me if I'm wrong) which are not usually standard. Some of the ones I've seen are like acme or square, some are V threads, but with multiple starts.

Here's a random pic I found on the web:

GenePoole is correct, thats the thread I was wanting to know about.
