Inside the M4 Carbine Factory: How the US Army's Rifle is Actually Made
Exclusive access inside the high-tech factory building the M4 Carbine for the US Military. 🇺🇸⚙️
Every soldier trusts their life to this 6.5lb machine. But how is it born? In this documentary, we follow the complete journey of an M4 Carbine—from a raw block of 7075-T6 aircraft aluminum to a fully automatic weapon ready for deployment.
Witness the 10-ton drop forges, the 5-axis CNC milling of the lower receiver, the chrome-lining of the barrel, and the intense high-pressure "Proof Load" test that ensures this weapon never fails in combat.
