These magazines may have some rust / pitting as shown in picture They may have little or no bluing but should function fine. Picture is of the worst One I could find.
Original SKS Part will fit ALL Models of the SKS rifle.
These may need some minor fitting although most will install with no fitting.
Remember, when installing or removing an SKS magazine, the Bolt MUST be open to avoid damaging the magazine..
If you are having problems installing an SKS magazine,
SKS Magazines can only be installed and removed from the SKS with the bolt locked in the open position, if this does not solve the problem, the next question is, with the front of the magazine locked into position, is it that the back end of the magazine is hitting the trigger group not allowing it to seat all the way into position? If this is the case, you may have to slightly file the leading edge of the magazine until it will pivot into place.
