I'm been getting back into Perfect Dark due to its 20th anniversary, and after re-discovering the Laptop Gun, I knew what I must do.
(Even though I have about 52,342 unfinished projects already...)

This is just a rough initial prototype to test out the size/shape. This took a bit of figuring since there aren't many good reference pics.

At work I recently got a ton of 1/4" MDF for free, so I actually have the freedom to make test parts without worrying about wasting material.
