Well I just finished building my 70th AR lower, and by mine I mean the number of lowers I've built, not I own 70 lowers. For those that don't know, in addition to my other crazy hobbies and part time occupations, I build and diagnose ARs for people. And I get asked all the time about how many I've done, but never really thought it was that much until I was at HiCaliber this afternoon talking with some of the guys I know about this being number 70, and several of the others had a heart attack. I don't keep track of uppers since I do lots of small stuff on them, like swapping barrels and rails (Yes people actually pay others to swap rails). So it got me thinking, how many have YOU built? And I've only been an AR guy for just over 2 years and being a "armorer" on the side for a little over a year and a half I think.
