People.......I never said an AR is not a good option. I'm saying different house layouts and locations have different optimal choices for long guns for home defense.
A shotgun is a good choice in a small home with close neighbors. Period.
It just drives me crazy when guys just blabber "ar" as the end all be all choice and then double down and say a shotgun is under powered on top of it.

If your getting into NFA why not an SBR? Easier to shoot and more ammo on hand.
Btw who said anything about nfa? An 18.5 inch barrel is a great length for a hd shotty.
