CNC Warrior makes a AK-74 style muzzle brake that reduces recoil and it fits over the standard 14MMx1MM LH threading typical of a 7.62MMx39MM AK/AKM carbine or rifle.
The AK-74 type muzzle brake is pretty effective. It may not be the absolute best thing you can buy to reduce muzzle climb and recoil, but it's better than a barrel nut (designed to protect the barrel threading) or slant comp (designed to reduce muzzle rise).
There's a plethora of other options available now, some of which are listed below:
Arsenal AK-74 muzzle brake (only usable with an adaptor on standard 14MMx1MM LH threading, so far as I know)
Arsenal AK/AKM muzzle brake (standard on some of their current 7.62MMx39MM)
Damage Industries (various brakes)
Those are all that I can think of right now, but I'm certain there are others.
Where and when you buy will obviously affect what you pay, so shop around.
