CAD fans, gather 'round! This build from expert LEGO gun-maker, Nick Brick, is going to make you salivate! This fully-automatic tweapon is one of the main ones used by the Atlas Corporation. It is an average damage-per-assault rifle that works in four round bursts. Nick Brick had this to say about his recreation:

"Utilizing an internal Formcaster 3D Printer, the integrated Munitions Rifle (IMR) can print ammunition while on the battlefield. 

This LEGO replica of the IMR is based on the one used in the first campaign mission, "Induction", in Call of Duty Advanced Warfare. Working features: light-up red dot sight, flashing printer status module, moving trigger, and fold out/slide out tube magazine. 

Non-LEGO elements used: Brickstuff lights for the sight, LifeLites for the printer status module, and EclipseGrafx tiles for the liquid matter tank lettering."
