M4 Carbine
The M4 Carbine was born in the early 1980s as a response to the need for a lightweight, versatile weapon that could be used by the US military in a variety of situations. Its design was based on the AR-15, a civilian rifle that had gained popularity in the 1960s. The M4 was specifically designed to be used by infantry soldiers, and it quickly became the standard issue weapon for the US Army, Marine Corps, Navy SEALs, and other special forces units.
