Back in the '90s I had a 1954 Russian model, paid $150, like new packed in a box of cosmoline. I heard they were as cheap as $50 just before I bought that one and plentiful. Then they went to $250, $450, now hard to find originals.
The old Chinese one's were just as good.
Buddy bought a newer Chinese Norinco sks, looked the same and shot well but had a shellaced pine stock and painted barrel and receiver and stamped receiver instead of milled. And I doubt it had the chrome lined barrel the originals had (protects the barrel when shooting the cheap surplus corrosive ammo).
I put a Dragnov style sniper stock on mine with a adjustable cheek piece (handy if you add a scope), flash suppressor and bipod.
It comes with a 10 round fixed magazine but they do have detachable one's. I had a 5rd for hunting and a couple 30rd for fun. I picked up rear receiver cover already drilled and tapped for a scope cheap so I didn't have to mess the original one up. Used to be all sorts of stuff for sks's in Sportsman's guide and Cheaper than dirt catalogs, not sure if they still carry all that stuff.
Ammo was $2 a box of 20 back then not even buying them in bulk.
I did pick up some good brass hunting rounds for it once a harvested one deer, one shot.
The Ruger mini 30 is also chambered in that round.
