Mac Thread Adapter?

At the present doing online searches and I think I found what I am after, but figured I'd toss it out there. As I understand it the Mac-10s have a non-standard thread pitch. I'd like to run a can we already have that is full-auto rated. I have adapters for 1/2x28 and M13.5x1 LH; neither of which will work. Options? Thanks much.


9mm mac10 right? i think the threads are 3/4x10 for the 9mm. finding an adapter for that may be tricky!

buena suerte amigo


Bought a US Machinegun adapter for a certain company in Vernonia to test a Mac specific threaded suppressor on a regular 1/2x28 barrel.


They make good stuff.

I looked through their site, I didn’t see the opposite version of this guy. Which I’m thinking is what you are looking for?

BTW, most just have their Mac threaded 1/2x28.

maybe check and see if your suppressor has an 3/4x10 front cap available?


Mine came with a Bowers suppressor and you have to constantly tighten it back up after each mag dump.
The adapter will really have to be torqued to keep the 3/4x10 threads in place.

    A relative of mine recently went through this place to purchase a handgun. They were rude to her, lied to her, and must be new to this FFL stuff...

    This is the closest gun close to my house and they have always been super nice. I have bought two guns off them and sold one of mine to them.
