Frequently Asked Questions

How do you remove the bolt from a Swiss K31 rifle?

To remove the bolt from a Swiss K31, first ensure the rifle is unloaded. Pull the bolt handle all the way to the rear, then depress the small lever located on the right side of the receiver. This will allow the bolt to be withdrawn from the action.

What is the purpose of the longer rear trigger guard screw on the K31?

The rear trigger guard screw on the Swiss K31 is longer because it is designed to thread into the receiver's tang. This provides a secure connection for the trigger guard assembly, ensuring proper alignment and function of the trigger mechanism.

Why is it important to keep the K31 chamber clean?

It's important to keep the Swiss K31 chamber clean because the rifle has limited extraction power. A clean chamber reduces friction, ensuring that spent casings can be reliably extracted from the firearm after firing.

Can the trigger mechanism of a Swiss K31 be easily disassembled?

The trigger mechanism of the Swiss K31 is generally not recommended for routine disassembly. Its two-stage trigger is considered exceptional, and key components like the trigger and bolt latch are flared in place, making removal difficult and unnecessary for standard maintenance.
