Frequently Asked Questions

What is the 'Scott system' in firearms, and why is it significant?

The 'Scott system' refers to a specific type of top lever work system in firearms, highly regarded for its effectiveness. Master Gunsmith Jack Rowe notes it's used by many top gunmakers like Holland & Holland and Purdey, indicating its superior design and reliability in firearm actions.

What are the key steps involved in disassembling the safety mechanism of a side lock firearm?

Disassembling the safety involves removing a small nut securing the thumb piece to the safety slide, then removing the slide itself. A specialized safety spring, similar to a sugar-tongs clip, also needs to be carefully extracted.

How is the top lever spring removed from a side lock action?

To remove the top lever spring, a small tool is used to push the lever over. The tool then holds the lever in place while the back end of the spring is lifted and the spring is slid out.

What is the function of the underbolt in a side lock firearm action?

The underbolt is the primary locking mechanism that secures the barrels to the action. While the front bite may act as a guide, the rear bite of the underbolt performs the critical work of locking the firearm.
