this is what i did after researching here and akfiles:
1) consult the document on cnc warrior site http://www.cncwarrior.com/v/vspfiles/Barrel_Threading.pdf
2) remove muzzle nut from Romak
3) measure barrel size
4) order kit from cnc warrior based up the recommended size
I had to go with 1/2 - 28
5) order brake that i liked with jam nut
6) followed directions and watched a few u-tube video
7) got the tools and oil and did the job.
I have been wondering the same thing, I just picked up a Romak 1 but the barrel seems a little longer in front of the front sight than a standard AK..Havent measured it yet, but was considering threading it and installing a birdcage style hider from CNC warrior. Not sure if it will be long enough though..Has anyone done this on the Romak?
It appears they set the front sight base (FSB) to the rear a bit further. That is unusual on a 7.62 rifle with a standard FSB. The 5.45 rifles in the '2'series., WASR, SAR, WUM 2 etc., had the longer exposed barrel because the 22mm front end of the barrel was cut away (neutered) and it was longer that the normal threading area on a AKM type barrel.
Some brakes will fit a longer muzzle thread area but not the slant or barrel nut.
If the diameter is .550" +/- it can be threaded for standard 14mmx1 pitch.
Or get one of the 24mm adaptors and use one of those type muzzle attachments.
AKblue, thanks for the response and info. I can see the issue i'm going to have is finding something with a long enough internal thread. Hopefully I can find something I can thread enough on there to engage the retaining pin.
