I had fondled an AR15 in a gun store while with my Dad when he was buying his first gun (a Beretta highcap .380 -- beautiful gun, wish we wouldn't have sold it). This was probably around 1986-87. I didn't know much about AR15's at the time. Truth is, that was probably a "preban" Colt that sold for $700, with 30 round USGI's going for $12.
About 6 months later, at a recruitment function for the USAR, I got to handle an M16A1. After handing the AR15, flipping the selector lever to "auto" was an experience I'll remember forever. I didn't fire it, but will never forget the significance of that second, backward motion flip of the lever. I didn't need the college money, and my parents (while proud) were apprehensive, but wanted the adventure.
Within the year I'd have my hands on one that I aptly named after my first girlfriend. Heck, The drill sergeants said we had to name ours, so.... I slept with it, shit with it, and slept with the carry handled threaded through my belt so my Basic Training comrades wouldn't steal mine on night patrol in the field. The point was weapons security. Anyone else remember being a private E-1 put on guard duty over your platoon's M16's and having a Captain come up and try to take one? Do you remember what you're suppose to do?
I went to basic back in 1988 (long time ago, huh?), but didn't own my first AR15 til 1998. Guess what? It was my wedding gift from my wife. Almost brings tears to my eyes....
