Here at forerunner 3D printing in our never-ending quest to test the limits of what's possible with 3D printed parts we decided it was time to take our previous AR15 live fire testing to the next level with a fully automatic M16. We hold a Federal Firearms License (FFL 02) and also are a special occupancy taxpayer (SOT 07) for manufacturing. This means we're able to produce fully automatic weapons for testing and evaluation of new technologies. The rifle you see here is a test article that was built to see if we can Full Auto rate 3D printed components like lower receivers and hand guards.
