Frequently Asked Questions

What causes slam fires in an SKS rifle?

Slam fires in an SKS can be caused by a worn or jammed firing pin. If the firing pin doesn't retract properly after firing, it can strike the next primer prematurely as the bolt closes, leading to an unintentional discharge, often in full-auto.

How do you fix a slam fire issue in an SKS?

A common fix for SKS slam fires is replacing the original firing pin with a spring-loaded version, such as the Murray's SKS Firing Pin. This design ensures the pin retracts reliably, preventing it from sticking forward and causing a slam fire.

What tools are needed to replace an SKS firing pin?

To replace an SKS firing pin, you will typically need a bench vise to secure the bolt, a punch that matches the diameter of the retaining pin, and a metal hammer to drive the pin out and back in. A Q-tip is also useful for cleaning.

What is the benefit of a spring-loaded firing pin?

A spring-loaded firing pin, like the Murray's SKS Firing Pin, is designed to automatically retract after striking the primer. This spring tension helps ensure the pin doesn't remain extended, which is crucial for preventing dangerous slam fires.
