BB-420 Carbine

This is a toy for cosplay or display purposes only! Never brandish this as a real weapon or bring it out in public, this is a toy modeled off of a REAL LIFE firearm, treat it as such. Just because you know it's a toy, doesn't mean other people will. Enjoy, be safe, and be smart!

This was big project for me and I am very pleased withed how it has turned out. Modeled using nothing but a 2D image of an FX-9, tracing and some imagination in Freecad! Customize it to your own liking with the Provided step Files! If you're looking for something akin to a nerf gun this is NOT for you, even the cheapest nerf gun will outperform this in every way, if yoy can even get it to fire. It still makes a great cosplay prop or something cool to put up on your tool rack.
