SKS Dragunov stock disassembly. Help please.
My father bought an sks and had a dragunov stock put on it by a local gunsmith. it desperately needs cleaning, plus he recently bought a tapco mag to put in it and im offering to install that for him. However, i didnt know he had this crazy stock and i have no idea how to get it off. Either the trigger group is jammed or the upper receiver has to come off first. can someone please at least tell me where to begin, i already know how to take a wooden stock off. its just this crazy thing.
