Portable, bipodal machinegun that's not tremendously oversized.
About this creation
I'm very satisfied with this MOC. Sure, I cheated a bit by using a rifle that had the front sight broken off, but who doesn't have at least one rifle with that tip busted? Heh. I don't have a lot of actual bricks so I surprised myself when I found 3 box wrenches to build it with.
Alex, the "round brick" is a Technic 3/4 pin, part 32002 (http://peeron.com/inv/parts/32002). The full parts list is: Minifig rifle x1, minifig hand x1, technic 3/4 pin x1, closed box wrench x3, minifig binoculars x1. Thank you!
Some have asked about the strength of the bipod due to its construction. The front "leg" of it stays in place very well thanks to its friction against the lip of the 3/4 pin, and the rear leg stays in place as long as everything is pushed together tightly.
