there is one flaw in the sks however, if that reciever pin shows wear it is prone to heat up and become brittle over time. I switch out my reciever pins every year depending on how much I have used it in that alotted time. But if that pin becomes brittle there is a significant chance of that pin snapping mid-fire and that bolt going right through your head. Vietnam vets say that the SKS killed more VC than we did due to the inferior sheet metal they used on their SKSs. Just ber for warned, keep a few lying around the house. :---
