My survival weapon is an Arsenal AK-104 clone. I tried to love the AR, I really did, I just couldn’t get past the jamming issues. I even went to an Adams Arms gas piston system which jammed so severely that I would have been killed if it were a survival situation.
My AK has never given me a single issue and gobbles up all ammo types like a dream (5.56×45 vs 7.62×39 is another aspect to consider). At this point my commitment is total and I’ve lost interest in most other weapon systems. The thought of trusting my life to anything else makes me nervous.
