M16A4

The modernized, updated version of the AR15 platform, currently in use by the United States Army and Marine Corps. While in less numbers than the M16A2, and generally only used by frontline units, it is arguably better than its predecessor. The M16A4 features a picatinny rail, a railed fore grip, detachable sights, and a 1:7' rifling, rather than the 1:12' and 1:9' rifling previous models had, which equates to better power and accuracy. The M16A4 is, essentially, an M16A3, but with a safe/semi/3-round burst selector switch, rather than a safe/semi/fully-automatic switch.

Standard magazine capacity is 30-rounds of M855 or Mk. 262 5.56x45mm ball ammunition. It is gas-operated, with a rotating bolt. It is air-cooled, with an external, detachable magazine, peep hole sights, a forward assist, and a charging handle mounted on top of the receiver, behind the picatinny/carrying rail.

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, along with its predecessors, spare the M16(A0) are unworthy of the negative press they receive. They are great rifles, but the first version, which was heavily modified by Lyndon Johnson's DoD, has stained the M16/AR15's reputation, due to the reliability issues faced previously.

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.

M16A4

The most bitched about weapon in Call of Duty 4.

M16+Red Dot Sight+Stopping Power=The bane of COD4 fanboys and the main setup of losers.

Sucker 1: "oh no! I was just killed by the M16! What a noobish gun! I have to go complain about it on an internet forum, because if I do, people will listen to me and stop using it!"

M16A4 user: "Quit your bitching, it's in the game, so it's fair!" (It isn't, by the way)

Me:"Call of Duty 4 sucks"

M16A2 

Noun-Eugene Stohner's pride n' joy... the M16A2 is a later version of the M16A1, the M16A2 is slighty more reliable than the A1, another notable difference is the firing modes... A1 goes on full-auto, while the A2 is limited to 3-round-burst, this is because in the Vietnam conflict soldier's would needlessly waste thousands of rounds, because of the thought that Charlie may be hiding anywhere... and the ratio of rounds to kills was about 1,000 rounds for one kill.

That M16A2 is a Colt!

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.
