1. The AK is not a great platform to suppress. The gas piston vents gas, smoke and noise right at the gas block.
2. AK threads are notoriously crappy. Because of this, suppressors for AKs typically have excessive clearance around the bullet path. This generally means they are louder than suppressors for other guns.
3. On your rifle, the threads on the barrel aren't even on the barrel, they're on the gas block... Its not only important to have them check for concentricity, it's important to have them checked by someone who really knows what they are doing.
4. After you do all of that, the suppressor performance is still going to be underwhelming, especially on a short barreled AK.
If I had one suppressor, it wouldn't be a dedicated AK suppressor. If I had 10 suppressors, one of them wouldn't be a dedicated AK suppressor.
