My firing point was far right and I did notice that one of the suppressors at the other end of the line was much quieter than the others when we were shooting. There was little difference close in the different models but with me farther away, there seemed a big difference. Problem is I have no idea who was shooting it and which suppressor it was.
I think if we'd stood 50 or more yards away when we were testing them, we'd have noticed a bigger difference. To my ear and from where I was shooting, there was only one that stood out a quieter than the rest. I think that mostly it would be a choice of price and mounting options as the main difference between the rest.
Also a question, a ffl dealer friend of mine told me that if I went and started getting class 3 stuff, the ATF and FBI could come in and inspect my entire gun collection. He said it could be any time they wanted, any time of the day or night. He said that if I got a suppressor, I'd sign away all my rights to privacy. Is this a problem or is he feeding me a line. BTW, he has one class 3 weapon and has never been inspected (for that). All my stuff is legal but I'd rather not have everything pulled out and serial numbers recorded.
Also, thanks for the pics.
