I just got my first suppressor, its an AAC sdn6. I know its not the best and that the mounting system has its issues, but it was one of the few that was available when I purchased. I mounted it to my 300 blackout following the instructions and it had some wiggle as the instructions said it would. I've fired about 100 rounds through it. I want a second opinion, because if you look closely at the exit hole there is a slight irregularity to it. Could a baffle strike really be this mild? Or is it just how the suppressor was manufactured?
