If you would really like the higher capacity, then as others have mentioned, maybe an AK would better fit your criteria.
I have a couple SKSs (and some AK actions) and from what others have said about aftermarket high cap detachable mags for them are, from my recent experience, absolutely correct. My first SKS, a Nroinco, was bought a long time ago before the import ban and configuration rules. I had heard bad things about the high cap mags and really didn't like the looks of them both in build quality and when they are attached to the rifle so stayed away from them. I never actually fired an SKS with one until a couple weeks ago. I did install a factory Chinese 20 round fixed mag on it and it has worked very well. The recent Yugo SKS is totally stock, no issues there.
A friend of mine recently purchased a used Yugo with detachable 30 round mag. Mag manufacturer is unknown. Had I known he was looking at it, I would have guided him away from it. He had brought it to the range one time (its first time out with him) for me to examine and run a few round through it. The mag quality was as expected, not very good, particularly the thin sheet metal used. Insertion and extraction of the mag is not very fast as things have to be inserted just right to lock in. Uses the existing mag latch to lock in and release. Need two hands to remove the mag, one to actuate the release and one to pull the mag out as it is tightly held in place by the stock. On a few occassions, the nose of the round being loaded was not elevated enought to enter the chamber. Where the front "duckbill" extension meets the mag body, there is a small open space. In one instance, the mag misfed and the round was actually protruding through that small space. I had mentioned to my friend that there are factory 5, 10, and 20 round fixed SKS magazines available if he would like to convert it back to its original form.
. So it will have to be the SKS any tips for tricking out an SKS?
