This video delves into the Colt OICW Mark II LMG prototype, a sophisticated but ultimately unadopted weapon system. It highlights the advanced LE1020 external piston system, designed with lessons from the SCAR program, featuring user-accessible gas systems and carrier tilt mitigation. The LMG variant showcased a quick-change barrel and a robust bolt carrier group engineered for sustained fire, representing a significant, albeit obscure, development in Colt's history.

The video critically examines the US military's adoption of the 6.8x51mm (.277 Fury) cartridge and the SIG Spear rifle, questioning the necessity and practicality compared to previous options like 6.8 SPC. It highlights the cartridge's high pressures (80,000 PSI) and velocities (140gr at 3000 fps) enabled by hybrid case technology, but raises concerns about cost, barrel wear, and civilian availability. The host suggests 6.8 SPC might have been a more balanced solution.
