This is a Chinees model M SKS. To clear things up. These are not modified. They are the only SKSs to be made by the factory to take high capacity detachable mags. Specifically AK mags. Other SKSs have been modified to take duckbill mags, and even AK mags, but they often have feeding problems. These do not have any feeding problems. These are only going to get harder to find and more valuable.There haven't been any imported since 1994. The wood on this rifle is beat up but the metal is good. $550 or trade for AK.
