"My Walmarts here carry several different brands of AR15 in .223, 5.56 and 22lr."

I would think the lefties would encourage Wal-Mart to sell "assault" rifles chambered in .22LR. Nobody who buys one will be able to find ammo for it. ;-)

Yeah that AR15 in 22lr has the same “assault” effectiveness as a Ruger 10-22. Which is every 10 year old shooter’s first plinking gun.
They inflict terrible damage to water balloons.
