I would not mind an AR9 with something around a 7-8" barrel with folding stock for a bag gun.
I bought the AR9 with a 10.5" barrel I have now because I was not up to speed on the differences between the 9's and AR15 builds at the time.

I may not be smart but I can lift heavy objects

I have a shotgun so I have no need for a 30-06.....
