Duration: 11:07

Melvin Johnson Jr., a lawyer and Marine captain, designed innovative semi-automatic firearms like the M1941 Johnson Rifle, which used a short-recoil system and a unique rotary magazine, contrasting with the M1 Garand. His designs, including a lightweight LMG and the Spitfire carbine conversion, influenced later platforms like the AR-10/15. Johnson also pioneered modern Gatling gun technology by integrating electric motors, leading to advanced rotary cannons.

Quick Summary

Melvin Johnson Jr. designed the M1941 Johnson Rifle using a short-recoil system and a 10-round rotary magazine, distinguishing it from the gas-operated M1 Garand. His rotary bolt design influenced the AR-10, AR-15, and M16. He also created a lightweight LMG and pioneered electric Gatling guns.
