This is The LB9 file pack, this design has not been fully stressed tested, Feedback from anyone who decides to build this would be greatly appreciated. The LB9 is a mostly printed and DIY 9mm blow back semi-auto pistol that uses and AR-15 FCG, barrel, firing pin and buffer spring. Every thing else is 3D printed and common hardware that can be purchased at a hardware store and online. The LB9 accepts Glock mags and was design to accept metal bushings to help mitigate the heat from the barrel to the plastic. The lower receiver was designed to accept wood screws for reinforcement. LB9 build video an be found on my channel. For more designs and content, stay tuned and enjoy the sound of liberty!
