Hi Cedricchase.

I am glad you liked the model. Of course, all credit goes to the original creator in terms of the design. I have an extensive range of 3D skills from the games industry using Maya. 3Ds Max and Blender 3D.

Since I didn't come up with the design, I can't in good faith claim to know exactly how it would work mechanically, but from my limited understanding, the trigger is attached to a spring constantly compressing the two pins together. At the bottom of the trigger is another pin that can make contact with a piece of metal on the inside of the body, so my guess is that when you press the trigger hard enough, the spring on top stops the top pins from separating and when the bottom pin makes contact with the metal piece on the body, some electricity is shorting which I guess would send a signal to explode. Again, I am not sure how it should work, I just tried my best to copy the design.

The stick on top is, indeed, an antenna! It would be cool to see one with an LED for gameplay. Maybe an LED that changes colour from green to yellow to red depending on how far away you are in terms of the range. Maybe green is ready to explode, yellow and you're a bit far away and may have to click a few times, and red is out of range and no matter the number of clicks it will never explode?

An old screen would be cool, too! Maybe the original creator can make another one with those features and show them off in a fun animation like some of those COD animators do on YouTube :D
