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!

The BB-MPK is a functional prop/launcher and the unofficial (PLAS)TEC-9 V2. It is not a very powerful launcher, but still some good fun! Tolerances are quite tight in some places so sanding/filing may be required, but for best performance sand down the bullets and the barrel to reduce friction

There are two super cool remixes on Printables by Katfish Heavy Industries, I would highly reccomend checking out.
