Well it was a good idea but in the outfit I was with you had to carry at least 20 mags or 400 rounds no matter what gun you chose to pack.To my thinking it took about twice as many .223 rounds to do the work of the 7.62 plus the gun was worthless as a cane.Best part of the AR was you couldn't get in trouble about rust on your rifle as it didn't rust,it was discololation and the Gunny hated it when you pointed it out.
