Frequently Asked Questions

What material is used for the Gunwerks LR Series rifle action?

The Gunwerks LR Series action begins as a blank of 416 stainless steel. This material is chosen for its strength and machinability, forming the foundation for a durable and accurate rifle component.

How are critical dimensions precisely machined on the rifle action?

After heat treatment, critical dimensions such as the bolt bore and lug raceways are precisely machined using a Wire EDM machine. This process utilizes electrical current through a brass wire to achieve very close tolerances and ensure accuracy.

What quality control measures are taken during rifle action manufacturing?

Quality control involves checking the diameter and straightness of each action. The entire manufacturing process is engineered to produce true and concentric surfaces, which are crucial for enhancing the overall accuracy of the shooting system.
