SR25 ER MAMS install

[TheGerman]

Does anyone have or has installed the 7.62 MAMS break?

I been looking at it and can't figure out if you need to have a threaded barrel for it or not; I am assuming you do since it mentions a thread pitch but everywhere I've read about it all they talk about is shims.

Anyone know?

Yes the barrel needs to be threaded. The shims are for timing it, IE, making sure the post that is supposed to clock at 12:00, clocks at 12:00.

Generally they are 3/4x24, though they do make a 5/8x24 model now too. And a 5.56 model (1/2x28) now that I think of it, too.

Cool, thanks. Looks like I'll need to get it threaded.
