Are the sks' easy enough to modify to accept detachable mags?
short answer no
Worth mentioning that the Czechs tested the SKS against their VZ and decided that the SKS was the better rifle overall. Mostly from an ease of maintenance and production basis. I love my VZ dearly, the engineering is cool!, but if I had to choose which "take to war" it would be the SKS.
Don't choose if you don't have to! VZs are expensive, relatively speaking, but SKSs are still available cheap, so if you can, get both! I am not sorry I bought my VZ
