Designing the Lower Assembly

     I had some struggles deciding how to make a trigger system that would fit a 1.25" PVC pipe because the only designs that came to mind that would work with my plunger system were of the type found on the Nerf CS blasters, which were big and oddly-shaped. When I got home and took a look at an old airsoft M4 I had (which happened to have a transparent shell), I realized it had roughly the same plunger system that I have in mind for my blaster.

     This is the receiver from the airsoft gun in question. The trigger is both simple and effective, if a little rough. One problem with the trigger piece is that it was made for a gun that had a trigger in the middle of the receiver, whereas I would like a trigger at the back of the receiver for my design. Ultimately I can imagine this to be a simple fix.

     In other news, I have downloaded a program called Autodesk and have begun to make a digital mockup of my blaster design. You can expect me to publish images of the model in the future.
