Mac Thread Adapter?

[CountryGent]

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

Looks like US Machine-gun might have what I'm after. Will confirm on the morrow.

this may confirm that. call them.

Adapter for m11 in 9mm to make the 3/4 x 10 thread useful

Does any one know of a solution for this conundrum, making the 3/4 by 1o thread on a m11 into a 1/2 x 28, 1/2 by 36 or three lug???:laugh

Most assuredly. Thank you.

if US Machine-gun does not have the adapter they can re thread the barrel

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.
