The WM16 rifle, officially designated Rifle, Caliber 5.56 mm, M16, is a family of military rifles adapted from the ArmaLite AR-15 rifle for the United States military. It was first put into service in 1963, becoming the standard U.S. assault rifle by 1969, replacing the M14 rifle.

The standard M16 fires the 5.56×45mm NATO round, but can be modified to fire different cartridges with the addition of a new barrel, bolt, and sometimes firing pin. The original M16, A2 and A4 variants fire in three-round burst or semi-automatic, while the A1 and A3 variants fire fully-automatic or semi-automatic.

It has been largely replaced by the lighter M4 Carbine in the U.S. military but still sees use in training and is still widely used by other miltaries throughout the world.

Insurgency: Modern Infantry Combat[]

Two variants of the M16A4 are featured in Insurgency: Modern Infantry Combat - the M16A4 and the M16A4 M203.

M16A4[]


The M16A4 is an assault rifle available to the Rifleman class.


M16A4 M203[]

M16A4[]


The M16A4 M203 is an assault rifle available to the Grenadier class.


Insurgency[]


The M16A4 is an assault rifle featured in Insurgency.

With a low supply point cost of 1, high controllability, and high accuracy, the M16A4 is a very cost-effective weapon. However, the long barrel of the M16A4 and its lack of a fully automatic fire mode limits its close quarter combat capabilities. Furthermore, the presence of the front sight when attaching a red dot sight or holographic sight obstructs the player's sight picture.

Insurgency: Sandstorm[]

Two variants of the M16 are featured in Insurgency: Sandstorm - the M16A2 and the M16A4.

M16A2[]


The M16A2 is an assault rifle available to the Insurgent Forces. Compared to the M16A4, the A2 has access to a more limited variety of attachments due to the fixed carry handle. However, it is the only weapon that can use a 3x A2 scope.

Trivia[]

Insurgency

  • Prior to the "Insurgency: Nightfall" update, the M16A4 used flip-up iron sights instead of the carry handle.
  • In the Insurgency: Early Access, the M16A4 was actually a M16A3 with an unused M203. The change from the A3 to the A4 variant was most likely done to increase weapon diversity.
  • The "F90" imprint on the stock of the weapon is an inventory identification number.
  • The bolt catch doesn't lock back when the weapon is empty, much like the M4A1 and Mk 18. This is strange, considering that there are other weapons that have empty sequences.

Insurgency: Sandstorm

  • The selector switch and auto sear pin aren't visible on the right side of the M16A4 model, but are visible on the left side; the M16A2 does not have this modeling error.
  • The M16A2's rear sight is permanently fixed to the long-range setting.
