Rough Action Design

After looking up mod kits on eBay and simultaneously watching GMod videos on YouTube, I have thought up a design for the action and have drafted a rough MS Paint mockup of it.

It uses a direct plunger which is hollow and open  on the back end to fit the mainspring in. The bolt is held in place by two tabs on the side and will have a charging handle directly attached to it.  I know there is no barrel or tigger assembly yet. This is just the action.
