I got to shoot my son’s AR-15 a few times in the last couple of months. He has an alternate chamber and high capacity magazine that enables it to shoot .22 LRs. We were getting off a coupla dozen rounds, much cheaper than the .223s that are far more powerful. But the shooting was fun.
Our only problem now is finding .22 rounds.
