My military rifle was the FNC1. Wasn't until I became a civvy that I got exposed to the AR 15 platform a looong time ago .... I had contempt for them as I was a dyed-in-the-wool believer in the 7.62x51 as a battle cartridge, a close second to the .30-'06 and .303. I mean, if you're gonna shoot something, SHOOT IT!
My wife bought her AR 15 before I even considered one. Now I'm a convert, not because of the cartridge, but because it's a nice lightweight package that works and handles well. It's the ONLY semi-auto my wife will shoot.
Now I'm trying to ease her toward adding a Tavor to the inventory as it's non-restricted. So far that's not working .....
