Back when I used FaceBook, I was part of the NFAGuns group, and the Dead Air guys, including the owner, chief marketer, CEO, etc, etc, were active in the group and seemed to really care about their reputation. If any problem popped up, they would immediately address it.
I was at an outdoor gun range a few months ago, and this guy next to me had a baffle strike which threw his silencer out about 25 yards. Coincidentally, one of the guys from the YouTube Military Arms Channel (or it looked like him, with the beard), went over and introduced himself, examined the damaged silencer, took pics of it for examination, and said he knew Mike Pappas of Dead Air Silencers and that he would make sure the Mike got him a new silencer.
Their customer service seeems over the top, which is a good thing.
