Frequently Asked Questions

What causes an SKS rifle to slam fire?

An SKS rifle can slam fire due to a worn or improperly designed firing pin, like the original tapered version. If the firing pin gets stuck in the forward position, it can ignite a round when the bolt closes, causing an unintentional full-auto discharge.

How does Murray's SKS Firing Pin prevent slam fires?

Murray's SKS Firing Pin features a spring-loaded design. This spring ensures the firing pin retracts automatically after striking the primer and resets itself, preventing it from protruding forward and causing a slam fire when the bolt locks.

What tools are needed to replace an SKS firing pin?

You will need basic gunsmithing tools, including a sturdy bench vise to hold the bolt, a punch that matches the diameter of the retaining pin, and a metal hammer to drive the punch. A Q-tip is also useful for cleaning.

What is the correct orientation for installing Murray's SKS Firing Pin?

When installing Murray's SKS Firing Pin, ensure the flat side of the pin is facing downwards. This orientation allows the spring to function correctly and aligns the pin with the channel for the retaining pin during reassembly.
