A Lower for the Lima Six Belt Fed Upper
This video details the design and testing of a prototype 3D-printed lower receiver intended for the Lima Six belt-fed upper. Key design considerations include a high dovetail for a short belt feed path to minimize jams and a two-piece construction for optimal print orientation and strength. The presenter discusses findings after 600 rounds, including issues with gas deflection and potential improvements for takedown pin placement and bolt catch functionality.
