This video showcases the 'Mammoth 50,' a 3D-printed .50 BMG rifle project featuring a Ligamec Raptor-50 upper receiver. The build highlights the challenges and evolution of using different 3D printing materials, moving from PLA+ to Polymaker PA6-GF for improved durability, though structural integrity at glue joints remains a concern. It demonstrates the extreme recoil and power of the .50 BMG round, even with a custom muzzle brake and modified LaRue trigger, and tests the limits of 3D-printed components like the monopod.
