I will agree that he has a solid 3 gun choice with the rifle, pistol and shotgun. However, his whole universe is hunting, that's the only reason he has them. That's always the center of the discussion, hunting.
I've got my guns for target shoot, fun recreation, and hopefully the need never arises...self defense.
You do realize that the AR-15 is just like any other semi-auto rifle, one trigger pull, one shot. Other than the hi-cap magazine and evil looking black stock, whats the difference between the AR and the Remington 750 semi-auto series rifles?
What's more dangereous at 500 yards....a bolt action 30-06 or the 5.56 AR. I'll wager its the 30-06.....you know....those sniper rifles.
Its just a total dichotomy of outlook on the 2nd Amendment, he's entitled to his view of it, but don't "sneer" at my black tactical rifles.
I'm just really happy my dad didn't have a problem with me buying an AR, because that would have been an issue. He see's how much I enjoy this hobby, so he was like.....go for it!
