3D Model Description
Brutus: Fully Mechanical Full-Auto Foam Dart Blaster
Low hardware build: only requires rubber bands, resistance bands, and silicone oil — nothing else.
Brutus is a stockless, compact foam dart blaster built around the refined X-Gen mechanism. It shares the same proven operating system as Bastion, but features a more aggressive, brutal appearance with significantly more exterior detail.
The X-Gen system uses a counter-slide mechanism designed to provide smooth and reliable operation. Pre-primed cartridges drive the blowback system, while the foam dart itself is powered by resistance bands, giving Brutus a distinctive mechanical firing action.
It fires 92x19mm foam darts at approximately 55–65 FPS and features full-auto operation.
If required by your local laws or regulations, print the blaster — particularly the front end — in a clearly visible color such as bright orange.

- Files only — this is a digital product, not a physical blaster
