3D Printed AR-15 Upper: Protofirearms' PCR V3

The last "Biden's Bane" stream brought a lot of developers attention, one of those developers is our guest "Protofirearms." He is unaffiliated with any of the printing groups and is mostly on YouTube and Instagram. He has independently developed his own AR-15 upper, the "PCR V3," which is uses a different method than the Biden's Bane for heat management. With me to ask questions will be Freeman1337 (Representing the Biden's Bane Development team), SpookyDev (AR-15 lower Dev), and possibly more!
