While the James Bond types might think the AK makes too much noise, those of us who just shoot and/or hunt would judge a suppressor by different criteria.
Can you imagine spending a day at the range WITHOUT needing hearing protection, because the suppressor handles it for you?
How about hunting? I know I don't use hearing protection while hunting, yet being a hunter doesn't magically protect my hearing.
So, while a specops would choose another platform for suppression, the AK (or AR, or Remington 700, or any firearm) would be great candidates for suppression for my intended uses.
