M16

The M16 is a rifle in the Insurgency series.

The ^🌐M16 rifle is a family of selective-fire rifles chambered in 5.56×45mm NATO used by many militaries around the world, adapted from the ^🌐ArmaLite AR-15 rifle. It was first issued in 1963 and replaced the M14 rifle as the standard U.S. service rifle in 1969. Since then, it has had four advancements—the M16A1, the M16A2, the, M16A3, and the most recent (and most likely final) advancement, the M16A4. Since the late 90s/21st century it has been largely replaced in multiple U.S. military service capacities by the M4/M4A1 carbines.

The M16A4 appears in Insurgency: Modern Infantry Combat with two variants: the M16A4 and the M16A4 M203.

M16A4

The M16A4 is an assault rifle for the USMC. It is available for the Rifleman class.

As a standard rifle, the M16A4 provides reliable semi-automatic and burst fire at all ranges. Its lack of automatic fire may cause some issues in close quarters or when having to lay suppressive fire, but in general the M16A4 is a reliable rifle for most situations.

M16A4 M203

The M16A4 M203 is an assault rifle and grenade launcher for the USMC. It is available for the Grenadier class.

As the name implies, the M16A4 M203 has an M203 underbarrel grenade launcher attached. The weapon itself performs the same as the M16A4, but the M203 can load and fire single-shot 40mm grenade rounds to provide explosive support.

The M16A4 appears in Insurgency as an assault rifle for Security. It costs 1 Supply Point and is available for the Rifleman, Sniper, Designated Marksman, and Demolitions classes.

The M16A4's main draws are its low SP cost, good rate of fire, wide class availability, and high controllability and accuracy, the latter two largely owing to its long barrel and manageable burst fire. However, its length and lack of automatic fire limits how effective it can be in close quarters. The gas block front sight post is also not removed when attaching an optic, which can obscure the player's sight picture. Still, the M16A4 is a reliable weapon if close combat is not expected.

The M16A2 is an assault rifle for the Insurgents. It costs 1 Supply Point and is available for the Rifleman, Demolitions, Observer, and Commander classes.

The M16A2 is similar to Insurgency's M16A4, in that its main draws are its low SP cost, good handling stats, and wide class availability, while its main flaws are its lack of automatic fire and, in this case, fairly low fire-rate. The M16A2 has another drawback in that its attachments, most notably optics, are notably limited due to the M16A2's age and lack of modern rail attachment systems. Still, the M16A2 is a reliable weapon that can fare very well in the majority of situations.

The M16A4 is an assault rifle for Security. It costs 1 Supply Point and is available for the Rifleman, Demolitions, Observer, and Commander classes.

The M16A4 performs almost exactly the same as the M16A2, owing to how both are simply variants of the same weapon. Statistically, the M16A4's only difference from the M16A2 is a very, very slight 20 rpm increase in fire-rate. The M16A4 also has the advantage of being a modern weapon with rail attachment systems, as it is capable of equipping most attachments, especially optics. In essence, the M16A4 is a straightforward upgrade from the M16A2, but only to the slightest degrees.

Trivia

Insurgency

• In the Insurgency: Early Access, the M16A4 was actually a M16A3 with an unused M203. The change from the A3 variant to the A4 variant was most likely done to increase weapon diversity.
• The M16A4 used flip-up sights until Insurgency: Nightfall, when that model was removed and replaced with the carryhandle.
• The "F90" imprint on the stock of the weapon is an inventory identification number.
• The M16A4's 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 M16A4's selector switch and auto sear pin aren't visible on the right side, but are visible on the left side; the M16A2 does not have this error.
• The M16A2's rear sight is permanently fixed to the long-range setting.
