I can't tell you how many years I've waited on buying a AR because the "Markings" were Roll Marked instead of Panagraphed Engraved..! Now I can make my purchase and sleep well at night.
I think he's making a broader point about those out there that type too much, and shoot too little (aka keyboard operators). I sure wouldn't turn down some lessons from him; he has a lot of knowledge and on the job experience.
I post semi-frequently at ar15.com. I don't think there should be any comparison between number of posts made and number of rounds fired. It's a freaking hobby for most of us, not a profession. There's no need to tell anyone to type less, shoot more, nor does it make him sound cool that some of us have jobs that don't involve practicing shooting people. That's silly.
I'll shoot when my schedule allows it, as much as I please or as little as I please.
The only place i visit over there is the retro forum. Of course i cant see it at all due to I.S. dept restrictions blocking it at work which is stupid!!!
