He now says a shorty AR in 223 with a can on it is the way to go and also says that a .22lr variant of the AR is a great trainer. Well, you can't carry two rifles and a pack for shtf. Why be without the .22lr option? It only costs you 3/4 lb, $200, and a few bucks for subsonic ammo, maybe a lb of it, 100 rds of the 60 gr Aquila. Wth would you not want the 22lr option, for quiet foraging, removal of scouts/sentries, dogs? Beats hell out of having sonic crack call in enemies, or running out of centerfire ammo.
