No argument about RPK mags with full sized AK's. AKSU is a different story. People who have free access to F/A stuff, 45rd mags etc. and need a CQB weapon would probably go for a 9mm SMG instead of AKSU. I've seen enough of "police action" back home during early/mid 90's. Most camo wearing "big boys" had 7.62mm AK's. I only saw AKSU's in hands of traffic enforcement and street patrols. Both branches are classified as useless, greedy idiots even by Russian standards
