HUB direct thread mount for 7/8-9 threads?
- Thread starter Slowmo
- Start date
I’m hoping to find something off-the-shelf if possible, but if not, I live close to Shaw and can have Joe Jones make something up for me. The inquiry mostly relates to wanting to have my MK9 recored and maintain compatibility with my M10/45.
I’d prob just get Ecco to make you one. They may not bc 7/8-9 is so coarse.
The other option for you is to have your barrel double threaded and put .578-28 on the tip then use the Ecco adapter.

Best Mac 10/45 suppressor setup question
Just bought a Mac 10/45. While it's in NFA jail, I figure I might as well get a 45 suppressor too. Three questions: 1- Looking at a Bowers VERS 45 can. What other suppressor should I look at for FA? 2- What upper in 45? I hear the fat ghost upper is less gassy than the Lage mk2 upper. Any...

I double threaded my barrel. Has the original pipe thread and I made a shoulder that threads down the 5/8-24 to give my can a shoulder then I can use a 5/8-24 direct thread.
A 7/8-9 shouldn't be difficult with a lathe that will do 9TPI.

I asked for this when ordering a PS upper and they said no problem, which was cool, since then they’ve added it as a standard option on their site, for which I choose to take credit whether it has anything to do with reality or not. 😂

Nobody is currently offering direct thread hub mounts off the shelf in any of the old obsolete MAC thread pitches as far as i know. No 7/8x9, no 3/4x10 and no 5/8x11… only the modern finer thread pitches. The only thing available in those MAC threads would be thread adapters, 7/8x9-5/8x24 etc etc. I could be wrong, but I have never been able to find anything.
Best bet is to get a 1/2x28 or 5/8x24 stubby threaded barrel and then get a thread adapter to 7/8x9 that screws onto it and looks just like the MAC barrel, it keeps the gun looking original and classic but gives you the option of the modern thread pitch for direct thread mounts

Back when I owned a MAC I had my barrel 3 lugged and used the Bixler 3 lug mount which is rock solid. Like others mentioned, I would be concerned with a can unscrewing with the coarse MAC threads. I don't like holding the can myself to prevent loosening.
Today, I would just turn the barrel down for a 3 lug and remove the coarse threads like I did a long time ago as I have no use for the coarse threads. If I did want the coarse threads, I would do as others suggested and have it threaded in the front and use a 3 lug adapter in the front and have a smooth thread protector when I want to go back to the classic look.
To expand on that. I would probably have a classic look upper and then another upper with a dedicated 3 lug.

Barrels and uppers are cheap. Leave the OEM alone and get something modern is the general advice.
So does GSL https://otbfirearms.com/gsl-technology-mac-380-9-45-suppressor-gemtech-viper/ in the design that used to be made by Gemtech. I’ve got a Gemtech one and was able to reach out to GSL and (eventually) acquire a few extra locking collars for different uppers.
