M16A4

A modern, modular assault rifle, in use by active duty, frontline units in the US Army and Marine Corps. It is the forerunner to the M16A2, which was in use from the early 1980's, to even now. While in less use than the M16A2, it is more effective.

Arguably a better rifle than its predecessors, the M16A4 is a rifle based on the AR15 platform. It features removable sights, a picatinny rail, fore grip rails, detachable carrying rail, and is slightly higher quality than the M16A2, all around. It utilizes a direct gas-diversion system, along with a rotating bolt. The magazines are generally 30-round ones, loaded with Mk. 262 or M855 5.56x45mm ball ammunition. It has a safe/semi-automatic/three-round burst selector switch.

Reliability in the M16A4 is solid; one is capable of firing upwards of 1,000 standard, ball rounds through a decently maintained rifle, with STANAG magazines, without a single jam or malfunction. While disputably not as good as the AK platform, it is a far cry from the M16(A0), and is a step up from the M16A2.
The M16A4 isn't worthy of its tarnished reputation, in reality. The M16 was an AR15, heavily modified from Eugene Stoner's designs, by Lyndon Johnson's DoD.

M16A1

The standard-issue rifle for U.S. Servicemen in Vietnam. Designed by Eugene Stoner as the Ar-15 to replace the M14 (which was difficult to control while in full-auto). The rifle fired .223 caliber ammunition, which later became the 5.56 mm NATO round in widespread use today. The M16A1 "spawned" the current U.S. service rifle, the M16A2, as well as the A3 (full-auto A2), and the M4 Carbine, which is in use by Special Forces units around the world.
The M16A1's jamming problems had nothing to do with the design of the gun, the U.S. Government had told troops that the rifle was self cleaning, therefore the troops were not issued cleaning kits until 1968. After the kits were issued, jamming reports were nearly unheard of.

M16A2

The most widely known rifle in the world(next to the Kalashnikov AK47), the M16A2 is not fully automatic, but fires in three round bursts that are perfect for clearing rooms or long range attacks.
The M16A2 is comparable to the Kalashnikov AK74su.
