I think this looks very promising considering your budget. There's a video below with specs and a demo from AKOU. Personally I prefer the AK-74 style brake but they are loud as hell and I'm sure there are better ones on the market.

Yes, I saw that one and based upon that particular video I like it a lot. But it's the only video of it's kind on that particular brake [that I can find].
The muzzle device is a "brake" vs a "break".
You first need to determine the outside diameter of the barrel. It is likely not suitable for the standard 14mm x 1 pitch threading as it was not designed to be threaded. It may have to be threaded 1/2 x 28 right hand.
Some of the AK74 Romanian rifles had a 22mm threaded extension on the front sight base (FSB) and the barrel was never threaded. Some have amore standard AKM FSB.., it depends
They neutered the 22mm threads off the FSB in most cases.
This created a longer than normal setback as well.
Pics of the front end would help and the OP of the barrel.

OK there grammar Nazi.................
I ordered this device to add to the muzzle, just in the hopes it might fit [slender profile barrel as you'll see below]:
....by getting the
brake, threading it onto the adapter and then seating it in place on the muzzle. I planned on marking the barrel with the Allen screws and dimpling it at the 4 cardinal points and then thread locking them in place. Figure the same principle used in mounting a gas block to an AR barrel.
Here are 3 pics of the muzzle:
Of course, I'll remove the paint from around the muzzle as necessary and I'm hoping the whole thing works out...but in order for me to complete the job I have to order whatever
brake I plan on using. Mounting the adapter before having the
brake on hand makes no sense.
