I Printed an AR-15
This guide details the assembly and testing of a 3D printed AR-15 by Hoffman Tactical. It covers the use of specific polymers like PLA+ and carbon fiber nylon, design innovations such as integrated components and a clamshell barrel mount, and troubleshooting common issues like ejection failures and heat-induced accuracy degradation. The process highlights the experimental nature of 3D printed firearms and the importance of material selection for performance.
