I absolutely agree with Bori! I, as well, own both weapon systems and wouldn't give up either. However, I've been in the Nevada desert during silica storms, and although visibility isn't all that impaired, silica sticks and accumulates on everything fast! I brought one of my AKs for this particular session leaving it on the ground while firing pistols and trying to get my buddies Wilson Combat AR to cycle (the action seized with silica...a total headache to clean), only to find that the AK action still cycled great with 0 malfunctions and there was caked up silica in the receiver above the bolt assembly. It took lots of compressed air and even water to get the silica out of our guns that day. All I'm saying is if it were a survival situation, in those conditions, we both would have been happy the rifle designed to function with a handful of sand in the receiver was there with us! Even if it only gives 3" groups at 100yds. Heh
Not that this little anecdote was entirely related to the subject, but I want to give him a little reassurance with his decision. I still feel that both are the way to go. Actually, both and then many others too! (-;
