The Colt M4 upper receiver is a key component of the M4 carbine, which is a lightweight, gas-operated, air-cooled, magazine-fed, selective-fire weapon that fires 5.56x45mm NATO ammunition. The upper receiver of the M4 houses the barrel, bolt carrier group, and other critical parts of the weapon system.

The M4 upper receiver is made of high-quality materials, typically aluminum alloy, and is designed to withstand the stresses and high temperatures generated during firing. The upper receiver also features a Picatinny rail system that allows for the attachment of various accessories, such as optics, lights, and grips.

It’s worth noting that Colt Defense LLC was the original manufacturer of the M4 carbine for the U.S. military, but in recent years, other companies have also produced M4-type rifles and upper receivers.
