THE GUNSMITH BOOK IS CLOSED ON 1 AUG 2021. See blog post.
For safety reasons, all jobs that involve action work must be checked for headspace and test fired before the gun is returned to the client.
We recommend checking headspace before any significant gunsmithing work is done to modify a gun to a specific purpose. This is intended to protect our client’s from having expensive work done to a gun that may not be suitable for the purpose intended.
