SKS is probably the world's most under-rated battle rifle. IMHO, it is a better rifle than the AK (aside the AK having detachable mags). 7.62 x 39 can be had much cheaper than .223
Opinions are like bellybuttons, we all have one. SHTF, I would opt for an SKS and put the money saved into ammo. Could be wrong, I frequently am.
Take care when you get information.
The truth is generally seen, rarely heard.
