My SKS is a also a joy to shoot. I bought a cheapo bubba-ized Russian back when bubba-ized Russians were cheap. Someone had swapped the original bolt cover for one with a mount and crappy 4x scope. I gave the scope away, but I use the see through scope mount as a poor-man's peep and the rifle is more accurate than I am.
I have a 7.62x39 upper for my AR and although I have 30 rnd mags for the AR/AK, I honestly don't know which one I would grab in an alien invasion scenario.
I'm right about the metric system 3/4 of the time.
