I get loads of rifles that people have tried to "home tune" too, I blame these youtube video's and their "harmonic tunes" people know an overpowered rifle is illegal but feel the need to try it anyway. the impact's and wildcats are becoming more frequent as they start to offer up new additional items such as power plenums. Why people need or want to run these on a sub12 rifle is beyond my comprehension.

Still, it's all work for someone to put it right
