Credit to Ironkilix for his mechanism and initial design.
This is my first ever rubber band gun made of Lego. Primarily focused on modularity, the MRBG (Modular Rubber Band Gun) is split into seven units: the pistol (core module), rifle barrel, stock, prop magazine, prop scope, magazine, and mag extensions (for use with rifle barrel). The mechanism is not mine, and is essentially copied from a now-deleted video. Here is another video detailing the mechanism.
The prop magazine can fold in half to look like a larger caliber mag, and there is another prop magazine for the pistol. This prop mag attaches to the bottom of the handle and stores inside of it when unused. You will need an average sized rubber band to spring the trigger.
