This is my model of the U-100 Lastly, the standard issue sidearm of Nanite Systems Operatives in the game Planetside 2. I've split it into multiple parts for easier printing and painting. Some parts mechanically lock together, but most should be glued together.

The rail has been resized to actual picatinny rail dimensions.

I've just updated with files for the default optic. Like my other attachments, this requires an M3x0.5 8mm screw and 5.4mm wide nut.
