I think we are blowing this way out of proportion. Just pick a gun! If you like the AR then you get an AR, if you like the shotgun then go with the shotgun. Ya'll are coming up with off the wall scenarios. All you have to do is pick a gun not tell a story of how your choice is better than others. If you pick the AR and it needs a part then too bad he didnt say pick a gun and all the parts to go with it that may fail. If your gun fails then your out of luck. Use your gun wisley. GUN and AMMO, pick it!
