I have run a suppressor on an Ak. At the time it was a Gemtech HVT. I managed to find the QD mount - which was no joke. I used it on a Bulgarian Arsenal gun and a Vector Hungarian under folder, both made before the barrel import ban. I installed the flash suppressors and used a rod to ensure that they were concentric... to the best of my abilities anyway. It worked fine but that HVT was a big heavy beast.
AK's don't suppress well. Back pressure forces smoke and gas out of very seem in the gun. Around the top cover, action, mag well... It basically looked like an old truck whose engine was on fire and the smoke was just coming out the hood cracks. Having said all of that, it still is much quieter than shooting without the can. As stated the threads need to be concentric to the barrel and the bore... in an AK that isn't the same thing.
