MK16A4

> "The MK16A4 fires highly accurate 3-round bursts for precision takedowns. It's long barrel, great stability allows the shots perform best in mid to long-range skirmishes and firefights where you have the time and space to carefully target enemies. A single burst kills if all three shots land, so it's best to attack from a stationary position if you want to avoid straying off target especially at closer ranges".

It has improved accuracy and precision, but it is notably equipped with a removable carrying handle and Picatinny rail for mounting optics and other ancillary devices.

## History

### Background

The MK16 is an Assault rifle manufactured by Holt's Firearms Incorporated at 1961, After the request of the Panamoan military on an Assault Rifle that will heavily replace the Current MN14 rifle. Since it was not the first rifle to use their new 5.56mm Caliber, Problems didn't arose. Holt made the barrel lengthened to 20 Inches, which is the minimum barrel length of a Light Machine Gun or a Marksman Rifle. This was routinely augmented with a rifling twist of 8 Grooves and 1:7 Twist, Also due to it's long barrel, it outmatched shorter 5.56mm SDC rifles in terms of Muzzle Velocity, penetration, accuracy, stability and stopping power. When the Hyemen War started, Panamoan Soldiers were eager to use the weapon, as they are convinced by the space age looks and outstanding performance. The bore was chrome plated, and it's chamber.

The results from the extensive testing of the first MK16 Variant (XMK16) was good, it was praised for it's outstanding accuracy for up to 600 Meters, unrivalled penetration and stopping power compared to other 5.56mm Rifles, and was surprisingly lightweight for it's size. Only a few soldiers said that they should need a Carbine configuration, because of the size.

The MK16 was well praised by Soldiers during the first years of the Hyemen war. However, some soldiers demanded that the weapon should include a forward assist, to lessen the need for fixing their rifle before being caught off guard by the enemy. APMC Marines suggested a curved 30 Round Magazine, as it can lessen reloads and make it look like a true Assault Rifle (Because they have typical curved magazines). Soldiers in combat only complained about Ammunition shortage, due to how rarely used the 5.56mm SDC Caliber is used in the time. The MK16A1 fixed the reliability problems via forward assist, and a reinforced barrel. This also made it widely accepted by Soldiers, Especially who were struggling with the MN14 against KR-47 Users.

The MK16A2 implemented an updated iron sights, and a standard curved magazine, with a rifling twist of 10 Grooves and 1/7 Inches twist. The MK16A2 became the sole improvement at 1970. The MK16A3 is a fully automatic variant of the A2, looking physically similar.

After the adoption of the MK16A2, the MK16A3 was only issued to the Amphibious Panamoan Marine Corps. The MK16A3 was adopted in the summer of 2003, where the wider introduction of optical sights and accessory devices, the MK16A2/3 will excel at performance, but will fare poorly in terms of modularity.

The Armed Forces of the Panamoan Republic demanded Holt to create and manufacture the 4th Generation of the MK16 Rifle. This was repeatedly suggested by Staff Seargent Nick "Wolf" Bale of the APMC, as he stated that if the Carbine variant is modernized, then the MK16 Rifle should be modernized.

Holt started to design the MK16A4, not simply a customizable and accurized MK16A2; but also the most efficient and reliable variant of the MK16 Rifle. Modifications include: a reinforced 9090 Titanium Alloy rifled barrel, a flat top receiver to give way for optical sights, and a quad railed handguard for a large degree of customisation.

The rifling twist consists of 12 Grooves; 1 turn in 7 Inches, to further strengthen the accuracy, effective range and lethality of the weapon. Another modification is the reinforced 7080 Aluminum Alloy Magazine, to reduce fouling and jamming. The weapon's Titanium-Aluminide Alloy Upper and Lower Receiver and the quad railed handguard is cold-worked, reinforcing it's Durability in a similar fashion to Nevium Alloys. This reinforced body makes the weapon exceptionally durable against anything. It was further demonstrated that it can be used as a club and chop a slim branch of a tree with ease and without any physical and internal damage.

Holt made these modifications; not only just to meet the requirements and specifications of the Amphibious Panamoan Marine Corps, But to further maintain a good reputation.

When the Armed Forces of the Panamoan American Republic tested the weapon, they were greatly impressed in a similar way to the MG556 Grinder. Though the Fixed Stock is still a problem like the M16, Holt's Firearms Incorporated want to stay true to the MK16/M16's Appearance. However, the first MK16A4s that were ordered and tested were essentially accurized and customizable MK16A2s.

> "The MK16A4 is a the 4th Generation of the MK16 rifle. It is a MK16A2 that features a detachable carrying handle/rear sight, and a Rail Interface System handguard for mounting various accessories such as laser designators, rail covers, laser modules, foregrips and underbarrel grenade launchers to allow flexibility in most combat situations."

> - Holt's Firearms Manual (Early release)

The first batch of MK16A4s are essentially customizable MK16A2s with a detachable carrying handle rear sight, and a Rail Interface System handguard, had been introduced into service in April 6th 2007, wherein the APMC and the Panamoan Army expressed no complaints about it, as it is not different from the MK16A2, which was proven by various Panamoan soldiers, only stating that it's a fully customizable MK16A2, and it becomes an accurized MK16A2 whenever there's an optical sight mounted on the weapon.

But in as it reached September 7, 2009, the refurbished and upgraded MK16A4 became the standard issue for the Amphibious Panamoan Marine Corps, Panamoan Navy and to a limited extent, the Panamoan Army. With the MK16A4 being largely replaced by the ACR 5.56 in 2020. Not to mention the popularity of Holt's MK16A4 also caught the attention of Rubicon Industries, which prompted them to manufacture their own; which also further bolstered the improved performance of the weapon.

### Operation Sandstorm

The MK16A4 first appeared in Sandstorm, as the standard issue of the Amphibious Panamoan Marine Corps. It is present on every mission, as long as there are APMC Marines are included in the mission, It is sometimes painted with an Atomic Desert Camouflage, lowering the high visibility of the weapon. Most APMC Marines had there MK16A4s fitted with a cloth wrapped around it's buttstock.

There are certain MK16A4s used/or dropped by APMC Marines that are actually fully automatic, and a lower rate of fire, clocking at 728 RPM; although it retains it's high damage, high accuracy and long range coupled with low recoil makes it valuable to most players whenever they desired to use it.

### Black Pegasus

The MK16A4 appears in the events Black Pegasus with unique variants and standard attachments. It is a relatively common rifle, used by Amphibious Panamoan Marine Corps as their standard issue rifle, except that it is overshadowed by the ACR 5.56, MK416, MK416 CQB, MK16 SPR and the MK4 in any urban operations. The rifle is similar to its predecessor from Call of Duty: Sandstorm, with high accuracy, high power and a healthy rate of fire in every burst. Unlike Sandstorm, recoil was increased, although the amount is quite low. The MK16A4 retains the 30 round magazine from the previous game, but with a higher rate of fire, so the magazine will empty faster. The rifle is so common so running out of ammunition is generally not a concern. The player's allies will always be seen wielding whether it is a modified or unique variant version of the MK16A4.

During the conflict, Some have encounter MK16A4 variants with multiple attachments or skins that are unavailable in standard, though these variants seem to offer little to no significant advantage over the normal and unique variants with one or more attachments.

The most common variant is the 'APMC Custom', which simply consists of an ACOG Scope, AN-PEQ2/A and a Foregrip, this variant is held by almost every soldier, though it is somewhat rare to find one with a Foregrip.

The 'APMC Grenadier' from the name itself; it is attached with an MK203 Grenade Launcher and various optics, most commonly the XM21 Reflex Sight.

## Design

> "The MK16A4 is the 4th Generation of the MK16 rifle. The barrel is free floated; completely customizable to mount optical sights, laser designators, underbarrel devices and other accessories to suit the combat situation. It's refurbished and upgraded rifling twist rate is ensured for extreme accuracy, stopping power, while keeping a flat trajectory at long ranges."

The MK16A4 typically have industrial strength 9090 Titanium Alloy upper and lower receivers, which helps save weight, while not compromising durability and overall strength of the entire body. As with the MK16A2, it comes with a factory standard, aircraft grade fixed stock, for enhancing stability in aiming.

The MK16 is a lightweight, 5.56mm, air-cooled, gas-operated, magazine-fed assault rifle, with a rotating bolt. The MK16A4's upper and lower receivers and the handguard are made of **Titanium-Aluminide Alloy**, its barrel, bolt, and bolt carrier of 9090 Titanium Alloy, and its pistol grip, and buttstock are made out of Polymer. The RIS allows for quick attachment/detachment of STD-785 components. The M10 RAS Handguard allows for attaching multiple accessories, depending on user preference, with little weight increase. *Bizarely*, the MK16A4 with the standard M10 RAS handguard had a strange accuracy increase of 16%, compared to a MK16A2.

All MK16s had a typically long rifled barrel makes it exceptionally precise and deadly; it is able to take headshots without missing a shot at 600 meters, and provide a 70-85% accuracy 800 Meters. This approximately 1.2 MoA precision makes it qualified to be used as a DMR, however the MK16A4 can score an accuracy of 60-85% at 800 meters.

The refurbished and upgraded MK16A4 had reinforced 9090 Titanium Alloy barrel that has a rifling twist consists of 12 Grooves; 1 turn in 4 Inches, with a Right Hand Twist, to further strengthen the accuracy, effective range and lethality of the weapon. Another modification is the reinforced 7080 Aluminum Alloy Magazine, to reduce fouling and jamming on full capacity, while increasing reliability. The weapon's Titanium-Aluminide Alloy Upper, Lower Receiver with the railed handguard is actually cold-worked, reinforcing it's Durability in a similar fashion to Nevium Alloys. This reinforced body makes the weapon exceptionally durable against physical and internal damage. It was further demonstrated that it can be used as a club and chopped off a slim branch of a tree with ease and without sustaining any physical and internal damage, and able to destroy a car's side mirror with ease. The stated service life of the barrel is 250,000 Rounds. During factory tests the MK16A4 fired 200,000 rounds in full-auto or three round bursts without malfunctioning and not needing replacements for it's components.

## MK16A4

### Mobility

Despite sharing the same ammunition caliber as the AR805, Chevron M85 MWS, AAI M556, ACR 5.56,MK4A1 and the AR552C, It deals a solid 45 damage for up to the three-forths of the weapon's effective range, making it capable of delivering one burst kills before reaching longer ranges, where it will deal thirty three damage. It's lenght also has a benefit for its long effective range for its class, while not as long as other Sniper Rifles though it provides a formidable threat in both medium and long range.

The MK16A4 handling characteristics are good among assault rifles despite it's size. The MK16A4 allows the user to move at ninety percent of the base speed, aim down the sight in 250 milliseconds, and although it has a moderate hipfire spread and poor hipfire performance due to the burst firing and semi auto mechanism, the MK16A4 makes up for it with exceptionally quick reloads, taking 1.1 seconds to Reload Cancel the weapon. This speed is exceptionally quick, and allows users to be relatively safe when reloading and it is always best to aim down sights if the player wants the precision from the weapon.

The MK16A4 has the standard Assault Rifle magazine capacity of thirty rounds, or 45 with Extended Mags. The MK16A4 starts off with 150 rounds total when not using Scavenger Pro.

The MK16A4 has good accuracy. The iron sights may be a tad uncomfortable to use for some, but the MK16A4 has very low recoil in the burst, and courtesy of the burst delay, the MK16A4 will recenter perfectly for the next burst to ensue. This places the MK16A4 among the most accurate weapons in the game, which can help users in landing their consecutive bursts on target. The burst-fire, combined with the fairly high centerspeed, helps this even more so. This can allow it to put multiple bursts down range within an exceptionally small area in the same target, making it an Assault Rifle-DMR hybrid, that is capable of rivaling DMRs in long ranges.

The MK16A4 has the usual assortment of assault rifle attachments. The MK320 Grenade Launcher is a powerful tool in combat, and given the MK16A4 can easily get a one burst kill without Stopping Power, the MK16A4 can be a worthwhile assault rifle to use with a Grenade Launcher and Danger Close. The Shotgun adds a long range, low damage shotgun to the MK16A4. This is a notable improvement from the MK16A4's hipfire performance, making the Shotgun another worthwhile attachment.

The optical attachments has all standard assault rifle sights, but usually, the ACOG Scope outclasses the other optical attachments due to its great accuracy bonus due to it's low idle sway (Except for the Telescopic Sight that has higher magnification and idle sway). The ACOG Scope is one of the most popular attachments on the MK16A4 due to it's low recoil and idle sway, and makes the MK16A4 much more competitive in the face of long range combat suited for a legitimate DMR.

The actual recoil of the weapon is quite low, due to it's symmetrical design which is the same with the MK4A1 and since recoil tends to go backwards, Missing a shot isn't really a concern even for accurate players. So a Foregrip isn't entirely necessary; though it greatly reduces the recoil, rivaling the MK4A1 in terms of low recoil.

FMJ isn't necessary, as the MK16A4 already has elevated wall penetration by default. However, it can prove useful for players that blindly fire at cover, as the MK16A4 with FMJ can penetrate most surfaces in the game with little damage reduction. As the MK16A4's Ammunition is Full Metal Jacket and Armor Piercing by default.

The Heartbeat Sensor provides miniature radar that notifies players to the nearby presence of non-Ninja enemies and allies. Allies light up green or blue, while enemies light up red, while also hinting at the general direction their pulse is coming from. The Heartbeat Sensor doesn't bring any clear cut downside to the table, but its effect in combat isn't needed for experienced players.

In conclusion, the MK16A4 is a powerful long-range weapon easily capable of gunning down enemies to a long range. Its main advantage is its high damage at medium and long range, which bests most weapons in its class, which have five-four hit kills. As well, the MK16A4 has a good deal of precision to offer, making the player a very powerful nuisance from afar with this weapon. If longer ranges need to be accounted, the MK16A4 should be seriously considered to aid you. Only the MK-17 can easily outmatch the MK16A4 in long range firefights.

Due to the MK16A4's high accuracy, high damage, long range, lack of idle sway, minimal burst delay and swift reload time makes it an all around weapon in medium to long ranges, making it a versatile weapon in almost any circumstances.

## APMC Remarks

> "My first year in, I carried a Holt MK16A2. It was cool. Plenty accurate, more than reliable, fixed carrying handle, semi and 3rnd burst, did the trick. I was then issued a Holt MK4A1, semi and full auto. Really cool boomstick with the MODULAR package and the giggleswitch. But, fuck, that thing's barrel is too long for the gas system and overheated like nuts. It went through extractor springs like underwear. My last year and some change in, I was issued the Holt **MK16A4**. I am skeptical during the '06, but that was my absolute favorite weapon. Flat tap w/an ACOG, held a zero like no one's business. Immensely accurate and reliable, semi and 3rnd burst. That thing never burped, farted, coughed or puked on me, it was a DMR disguised as a 5.56 rifle. Just maintain her regularly and she'd rock your service as a soldier."
>
> - Master Seargent Chris Horvath, a former APMC marine expressing his praise on the rifle during his service, and his complaint on the MK4.

### Various APMC Marines

* "This 5.56mm Assault Rifle is a DMR in disguise, it can perform suppressive fire at diverse ranges, and deliver accurate shots like a DMR, punch harder than other 5.56mm rifles and carbines due to it's sniper-length barrel with a good rifling twist rate, but it's only bad at urban due to it's large size, so a mid sized Assault Rifle or a carbine is a key weapon to urban areas."
* "I have slogged through snow and mud and sand with my MK16A4; even got dumped into an open sewer with it and it has never given me a bit of complaint. I trust it like I trust my own arms."
* "This AR is damn durable to the point that mine fell through a hundred meters below a mountain and it still works well, with little jamming problems."
* "The MK16A4 is built like a brick outhouse with Panamoan blinds. You can pound on a mike foxtrot with it like it was a sledgehammer."
* "For every time I’ve felt out-gunned by those alien bastards shooting blobs of energy, or another bunch of humanoid soldiers spraying lead at me I have felt like Death himself watching their bodies come apart under a hail of lead from my MK16A4."
* "Looks like Holt made Rubicon Industries shut their doors with the performance of this Assault Rifle, heck, I'm gonna use it as a DMR!"

### Sean Wilcox

* "This 5.56mm Rifle really solved the flaws of it's previous versions, even if some people claim that it's essentially a customizable and accurized MK16A2."
* "All of the MK16s and it's upgraded variations have similar things in common; extreme accuracy, extremely lethal stopping power, long effective range, and a lightweight construction."
* "Holt made a great decision to use a 20 inch rifled barrel, giving it pinpoint accuracy at 800 meters, intense muzzle velocity, and highly lethal stopping power it delivered in every shot. Attach a Telescopic sight, and use the 5.56mm SDS-68 SS987 Bulwark cartridge on it and you got yourself a trusty Marksman Rifle."

### Nicholas Wolfgang Bale

* "I never hesitate to choose this Assault Rifle when there's a non urban combat operation, and it's always gonna give me a good fight against the opposition."
* "It seems to me that every other Interstellar species die from this rifle typically in three-four shots to the chest, and one or a two shots in their heads."
* "It was a wise choice for Holt to make the 4th Generation of the MK16 rifle to be fully customizable, as the MK4A1 was the carbine version that first got picannity rails, making it a fully customizable weapon, despite it's highly inferior performance."
