M4A3s

The M4A3 is a variant of the M4 carbine, a lightweight, selective-fire, magazine-fed, air-cooled, gas-operated, and blowback-operated rifle developed by John Garand for the United States military. The M4A3 was introduced in 1951 as an upgrade to the M4A1, featuring a longer barrel, a new stock, and a modified gas system. The M4A3 was primarily used by the United States Marine Corps and the United States Army. It was known for its reliability, accuracy, and ease of use, making it a popular choice among soldiers. The M4A3 was gradually replaced by the M16 rifle in the late 1960s. Despite its eventual obsolescence, the M4A3 remains an iconic symbol of the American military and a testament to the ingenuity of its designer, John Garand.
