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.

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.

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"
