The NSSF has made an attempt to portray these guns as the new sporting guns and Remington has specific models for that view.
The sporting use defense is risky, I think because:
a. Why can't you go hunting with a Ruger Model One? If you are competent that should work. If you want a semi - why not a 5 round magazine? You don't need 30.
b. Why can't you keep your hunting gun locked up at all times till you go hunting, etc.?
So I agree that Sen. Munchking doesn't know what he is talking about. I've taken my AR out in the field. But sports doesn't defend the RKBA. We could all be bow hunters.
