CNC Machined PCP Air Rifle - Wooden Mockup Before the Aluminum Prototype 

I needed to confirm my design before cutting metal and wood is plentiful and cheap and easy to cut. So it is made in wood for now.
I have chosen to take a modular approach so I can make corrections on any module as long as the changes do not affect the other modules. Hopefully I can minimize the number of iterations before arriving at an acceptable overall design.
