sks parts

I have been looking into buying a Tapco t6 or fusion for my Chinese SKS for a while and i was just wondering if the picatinney rail on the top of the gas tube blocks your Iron Sights. I really dont see the use for a Scope or optic unless you are hunting or Sniping. So anybody know if this happens?

This is going to sound silly, especially when I have used stripper clips for more years than I care to acknowledge. However, I can't seem to find a ten round stripper clip that works in the SKS. Everyone I have tried has been just about worthless. The rounds bind up as you attempt to charge...
