5.56x45 mm M4A1 - NATO
M4A1- an assault rifle (carbine), designed in the USA on the basis of AR-15 platform for 5.56x45 NATO cartridge. It was developed primarily for use by vehicle operators and fireteams, who required a more compact and lighter weapon than a standard full-length rifle, but using the same ordnance.

Introduction
Note
The M4 Carbine is a 5.56×45mm NATO, air-cooled, gas-operated, direct impingement, magazine-fed carbine. It has a 14.5 in (370 mm) barrel and a telescoping stock. It is essentially a lighter and shorter variant of the M16A2 assault rifle.
The M4 is extensively used by the United States Armed Forces and is largely replacing the M16 rifle in United States Army and United States Marine Corps combat units as the primary infantry weapon and service rifle. The M203 and M320 grenade launchers can be mounted on the lower hand guard of the carbine (see where bipod is attached on the photo). The distinctive step in its barrel is for mounting the M203 with the standard hardware. The M4 has semi-automatic and three-round burst firing modes (like the M16A2 and M16A4), while the M4A1 has semi-automatic and fully automatic firing modes (like the M16A1 and M16A3).
The M4 and its variants fire 5.56×45mm NATO (and .223 Remington) ammunition, and are gas-operated, magazine-fed, selective fire firearms with either a multi-position telescoping stock or a fixed A2 or LE tactical stock. The M4 is a shorter and lighter variant of the M16A2 rifle, with 80% parts commonality. The M4 is similar to much earlier compact M16 versions, such as the 1960s-era XM177 family. Some of those visual similarities are obvious in both weapons. The M4 with the newer, redesigned telescoping stock. As with many carbines, the M4 is handy and more convenient to carry than a full-length rifle.
