Dyna systems muzzlebrakes
For the newbies that might not know about Dyna systems. They have taps/dies for threading barrels and breaks themselves.
They will do custom brakes too in case you want one for that Yugo SKS to replace the grenade launcher tube.
Do you have a chart that shows what thread to use for what muzzle diameter?
Nope, I don't have that, but if you ask around here someone will know.
The problem with them is shipping delays.
I ordered a TAT 2 weeks ago.
They said it would ship same day and take 3 to 5 days via Airborne to arrive.
I called yesterday and after a 4 minute hold was informed my package was ready to go and would ship out today. I still have to wait 3 to 5 days for it to arrive.
Hmm? That sucks! Didn't know they were like that.

If you can get a hold of them, then they can answer most questions. They custom made an adapter for one of my Romies because it has the muzzle threads cut down. Jack
My order was just for the TAT, a $12 part.
I suspect that if it was for a complete system they would of been a little quicker with shipping.
Good link, I sure am eyeballing that 1/2x28 kit for one of my AR's, gonna bookmark that.
The standard size for AK-47/AKM rifle barrel threads is 14x1mmLH. The standard size for M-16/AR-15 rifle barrel threads is 1/2x28.
So unthreaded barrel semi auto AK rifles imported to the US are going to have barrels that are 14mm/.551" in diameter or barrels that have had the threads turned off leaving the barrel 12.3mm/.480" to 13mm/.512" in diameter.
The 1997-1998 imported Romanian 7.62x39mm rifles,milled receiver MAK-90,milled receiver MAK-91,and Norinco Hunter models never had the barrels threaded so they are 14mm/.551" in diameter.
The 1997-1998 imported Romanian 5.45x39mm rifles and SAR-2 rifles have 12.7mm-12.9mm/.500"-.508" diameter barrels.
Maadi rifles with unthreaded barrels have the barrels theads turned off and vary 12.3mm-13mm/.480"-.512".
I have threaded several Maadi,Romanian CUR-2 5.45x39mm,and SAR-2 rifles that had barrels 12.7mm-12.9mm/.500"-.508" with a 1/2x28 threading kit. Then bought AK-74 style muzzle brakes made for AR-15 rifles.
Just a thought about MAK-90's. I have one and the threads were turned off. They are still slightly there and barrel diameter has been reduced. Some MAK's like mine were inbetween models that were moded on the fly to import them.
I guess mine was 56S at one time and then moded?
