Thanks to the price of surp Czech ammo we can shoot the SKS like a 22! But it is dirty.I would strongly suggest stripping the bolt down after shooting. On a recent trip we shot off a couple hundred rnds.(try doing that with that with 30-30 ammo) and when I started to clean the bolt I noticed the firing pin wasn't rattling around as usual. We had no prob with it at the range so there was no real reason to suspect anything. Anyways,on tearing down the bolt, I noticed a little ball of primer? metal about the size of a dull pencil point stuck in the channel with the f/p! I had sprayed cleaner down the f/p slot and soaked it but you can see that if there is a solid piece of metal in there, spraying and soaking won't help.So who's to say what would have happened the next time it was shot. A little grease on the pin helps getting it out the next time. After the fist time it's easy!
