I think the AR platform is a pain in the ass to clean, but I still love it. Easy to shoot, shoulders nice, and lots of cool after market stuff to personalize it. As a kid I first saw it on the TV show SWAT and it was love at first sight. In the Army I've carried the M16A1 full auto, and then the M16A2 Burst(gay), and now the M4 still with the gay 3 round burst. I remember a live fire in Egypt in 1985 when I rocked nine 30 round mags out of my M16A1 and the barrel was starting to turn white hot. I probably screwed up the barrel, but didn't care. It was a CALFEX and we didn't even have any targets. We were just putting on a show for some Egyptian big shots.
