Frequently Asked Questions

How do you remove the bolt from a Swiss K31?

To remove the bolt from a Swiss K31, pull it to the rear until it stops. Then, push down the edged knob on the side of the rifle under spring tension and gently pull the bolt assembly out to the rear.

What is unique about the Swiss K31 bolt action?

The Swiss K31 features a straight-pull bolt action, unlike traditional bolt actions that require rotation. It uses a camming action within the bolt sleeve to unlock and cycle the bolt, allowing for faster operation.

Where did Swiss soldiers store their personal information on the K31?

Swiss soldiers stored their personal information, known as a troop tag, under the butt plate of their K31 rifle. This tag typically included the soldier's address, name, rank, and unit.

Why is it important to keep the K31 chamber clean?

Keeping the K31 chamber clean is crucial due to its relatively weak extraction system and the potential for a slightly oblong chamber. A clean chamber ensures reliable ejection, especially for handloaded ammunition.

What makes the K31's barrel bedding special?

The K31 is notable for its fully floated barrel, meaning the barrel does not contact the stock. This design minimizes interference with barrel harmonics, contributing to the rifle's exceptional accuracy, similar to target rifles.
