| I own a Yugo sks and it worked wonderfully when I bought it, but recently I cleaned it and took it out to the range and had to strike every round twice for it to fire. So my question is what could the problem be? Is it bad ammo? Is it perhaps that the firing pin isn't fully extending? One thought that occured to me but I'm not sure if it could cause this problem is the fact that I'm not sure which way the spring behind the bolt goes in. Right now, I have the end where the spring waves side to side inside the bolt. Any advice on the firing problem or the spring orientation would be much apperciated. Thanks |

Are you using the standard firing pin that came with the rifle ? What brand of ammo ? Has your trigger group been modified in any way ? The bolt carrier return spring being put in wrong would cause cycling problems and failures to feed, not light primer strikes. Your hammer spring could be worn out or damaged, which would result in light strikes on the firing pin, and that would explain the trouble. A less likely alternative is that the firing pin is binding up somehow in its' channel, perhaps as a result of cosmoline build up. The only way to get all the cosmoline out of the firing pin channel is to disassemble the bolt, remove the firing pin and extractor and then clean everything out. It's important to get all the cosmo out of the bolt because the cosmo can cause the firing pin to get stuck in the other direction, causing slam-fires (an extremely dangerous condition where the rifle fires as soon as you chamber a round). |

Just to clarify: You loaded rounds into the magazine, let the bolt go forward observing that a round entered the chamber, switched the safety off, squeezed the trigger and it did not fire the round but instead went "click." You then had to pull the bolt to the rear, pick up your ejected, unfired round off of the ground, load it back into the magazine, let your bolt go forward observing the round enter the chamber that previously failed to fire, squeezed the trigger and this time it fires the round, the action cycles and loads a new round. Please clarify if I mis-stated the malfunction that you are having. I just want to understand exactly what the weapon is doing. Edited to add: You have the recoil spring installed correctly. Wavy end into the bolt carrier. |

Thanks for the replies. To answer some questions... 1)I have always shot Wolf ammo, but I had switched types. (Originally used stuff in a black box, now I am using stuff in camo box) 2)I have not modified the rifle in any way. 3)BattleBore's description is exactly what I've been doing. |
If you don't have the proper punches, it's best to let someone who does do it. My recommendation is Ben Murray. He also offers an aftermarket spring loaded firing pin that is top notch. This practically eliminates any possibility of slam fires. www.murraysguns.com/sksown.htm |
If you want to do it yourself, this website has a good step by step guide to taking down your bolt. |

This is what worked for me to get the retaining pin out: Dasco Steel Punch (from lowes, $16 for the set) 3/4" socket Concrete floor Big effin' hammer Put the socket on the floor, lay the bolt across it, so that the pin will drop into the socket when punched, out, and whack the living shit outta it. First time getting the pin out is always the hardest. It get easier on subsequent removals. Good Luck! |
