I have no idea what you are talking about... can you elaborate?
Probably because I'm a modern gun guy, race pistols and AR's in competitions around North America... hence why this is my first SKS... just figured the price was great and every gun owner in Canada should own one (at minimum).
Izhmash is the factory the “Izzy” was made at ..... fewer SKS were made at this factory and the quality is, by some, considered to be better too. Most SKS were made at the Tula factory. There will be markings indicating this information on the rifle.
Probably a sticky about the SKS in the Milsurp section on here and YouTube and google can answer questions too.
