So here is a confirmed weapons list SO FAR.
It does look a lot like mw series.
XM8 (Assault Rifle):
The XM8 was a developmental U.S. Military designation and project name for a lightweight assault rifle system that was under development by the United States Army from the late 1990s to early 2000s. The Army worked with the German small arms manufacturer Heckler & Koch (H&K) to develop the system to its requirements in the aftermath of the Objective Individual Combat Weapon (OICW) contract, for which H&K had been a subcontractor to ATK. Although there were high hopes that the XM8 would become the Army’s new standard infantry rifle, the project was put on hold in April 2005, and was formally canceled on October 31, 2005.
AN-94(Assault Rifle):
The AN-94 is an advanced assault rifle of Russian origin. The initials stand for Avtomat Nikonova model of 1994, after its chief designer Gennadiy Nikonov who previously worked on the Nikonov machine gun. Official policy is for the Nikonov AN-94 to become the general issue rifle for the Russian Federation and Associated States (RFAS) armed forces, but (aside from around 1000 copies) it was still not in production as of 2006. Due to its complex design and expense its adoption has been very slow and it is in limited use; and it may never become general issue.[1] As of the beginning of 2012, the AK-74 (‘M’ variant) is still the general issue rifle used by the Russian military.
M16(Assault Rifle):
The M16 (officially Rifle, Caliber 5.56 mm, M16) is the United States military designation for the AR-15 rifle adapted for semi-automatic, three-round burst and full-automatic fire. Colt purchased the rights to the AR-15 from ArmaLite, and currently uses that designation only for semi-automatic versions of the rifle. The M16 fires the 5.56×45mm NATO cartridge. The rifle entered United States Army service and was deployed for jungle warfare operations in South Vietnam in 1963,[4] becoming the U.S. military’s standard service rifle of the Vietnam War by 1969,[5] replacing the M14 rifle in that role. The U.S. Army retained the M14 in CONUS, Europe, and South Korea until 1970. Since the Vietnam War, the M16 rifle family has been the primary service rifle of the U.S. armed forces.
SCAR(Assault Rifle):
Unclear whether its the H or L varient. The Special Operations Forces (SOF) Combat Assault Rifle,[5][6] or SCAR, is a modular rifle made by FN Herstal (FNH) for the United States Special Operations Command (SOCOM) to satisfy the requirements of the SCAR competition. This family of rifles consist of two main types. The SCAR-L, for light, is chambered in the 5.56×45mm NATO cartridge and the SCAR-H, for heavy, fires 7.62×51mm NATO. Both are available in Long Barrel and Close Quarters Combat variants. The FN SCAR systems completed low rate initial production testing in June 2007.
Magpul M4A1(Assault Rifle):
Unclear if in game, only seen on marketing poster. The M4A1 carbine is a fully automatic variant of the basic M4 carbine intended for special operations use. The M4A1 has a “S-1-F” (safe/semi-automatic/fully automatic) trigger group, while the M4 has a “S-1-3″ (safe/semi-automatic/3-round burst) trigger group. The M4A1 is used by almost all U.S special operation units including, but not limited to, the Army Rangers, Army Special Forces, Navy SEALs and Air Force Combat Control Teams. The M4A1 is especially favored by counter-terrorist and special forces units for close quarters combat because of the carbine’s compactness and firepower.
MP7 (Sub Machine Gun):
The MP7 is a German submachine gun manufactured by Heckler & Koch (H&K) and chambered for the HK 4.6×30mm cartridge. It was designed with the new cartridge to meet NATO requirements published in 1989, as these requirements call for a personal defense weapon (PDW) class firearm, with a greater ability to defeat body armor than current weapons limited to conventional pistol cartridges. The MP7 went into production in 2001. It is a direct rival to the FN P90, also developed in response to NATO’s requirement. The weapon has been revised since its introduction and the current production version is the MP7A1.
M249 SAW (Light Machine Gun):
The M249 light machine gun (LMG), previously designated the M249 Squad Automatic Weapon (SAW), and formally written as Light Machine Gun, 5.56 mm, M249, is an American version of the Belgian FN Minimi, a light machine gun manufactured by the Belgian company FN Herstal (FN). The M249 is manufactured in the United States and is widely used by the U.S. Armed Forces. The weapon was introduced in 1984 after being judged the most effective of a number of candidate weapons to address the lack of automatic firepower in small units. The gun provides infantry squads with the heavy volume of fire of a machine gun combined with accuracy and portability approaching that of a rifle.
Unknown Tri-Barrel Shotgun -Possibly 870 MCS (Shotgun):
The Remington Model 870 is a U.S.-made pump-action shotgun manufactured by Remington Arms Company, Inc. It is widely used by the public for sport shooting, hunting, and self-defense. It is also commonly used by law enforcement and military organizations worldwide.
Kriss Kard (Pistol):
The KARD’s barrel is fixed, rather than the tilting barrel system used in most conventional pistols. To provide inertia, a weight is located at the front of the gun which is actuated by the bolt. The weight, which tilts downwards during recoil, provides the same functionality (interia) as a slide on a regular pistol. By the time the bolt and barrel separate, the pressure inside the barrel will be at safe levels. A recoil spring pulls the bolt back intro battery (stripping a round off the magazine on its return journey).
M1911 (Pistol):
The M1911 is a single-action, semi-automatic, magazine-fed, and recoil-operated handgun chambered for the .45 ACP cartridge.[1] John M. Browning designed the firearm which was the standard-issue side arm for the United States armed forces from 1911 to 1985. The M1911 is still carried by some U.S. forces.
