FR8 Barrel thread pitch

[HumptyDumpty]

I've been digging around the internet, and can't seem to find this information. Does anyone here known the thread pitch of a Spanish FR8? I am assuming it's the same as a CETME, but I can only find info for new-production CETME barrels, and I have no idea if any of the Century guns retain their original threading. I wan to install a quick-detach muzzle device, for a can.

It's the standard M98 Mauser thread pitch...…..because it is a M98 or the Spanish M47 version of the M98.

Thread pitch gages will solve the problem. If you know any machinists to borrow one from.

The FR8 has a flash-hider installed, just like the CETME it augmented/served as a training aid for. I haven't removed it yet, and I won't until I actually have my suppressor, but it is these threads that I am concerned with. I don't know of any other Mausers that had flash-hiders.d the

Go ahead and pull the flash hider off it just screws on and off then you can measure the thread and pitch . I have had mine off several times but never worred about measureing it

Do you recall if it is right or left hand?

My bad, had the other end of the barrel in mind. Thought I had the pitch written down someplace as I removed mine but can't seem to find it. It was a metric pitch so I rethreaded mine for a M14 Flash suppressor castle nut. Then I could also put the Sionics suppressor on it and the m14 flash suppressor which is now on mine.

Thanks, I wouldn't think that they are different. Now I'll know whether I am turning the proper direction, or it is just tight. Six-plus decades can really seize up threads.

I believe they are the same, 15x1mm, right hand. I like the original flash hiders designated for cetme and FR8, they look good and are functional. And also important, original.

I have a yhm phantom on mine, its a hoot.
