I'm a lot like the OP. After some not so good experiences with the M-16A1 in the Army, I refused to buy an AR for about 40+ years. But then .gov and the antis started pushing banning them really bad. So, I finally broke down and bought a S&W M&P 15 just because they didn't want me to have one.
About a year or so later, I stumbled into a great deal on a Colt A2 Sporter that I just couldn't pass up.
Honestly, I don't shoot them much at all. I have 'em just because.
I am sorta interested in one of the super accurate ones, but I don't know if I'll ever break down and spend that kind of money. The two I have will probably be the only ARs I'll ever own. I'm just not a fan.
