Mk 19 Grenade Launcher

The Mk 19 is a belt fed, blowback operated, air cooled, crew served, fully automatic weapon that is designed not to cook off. It fires 40 mm grenades at a cyclic rate of 325 to 375 rounds per minute, giving a practical rate of fire of 60 rounds per minute (rapid) and 40 rounds per minute (sustained). The weapon operates on the blowback principle, which uses the chamber pressure from each fired round to load and re-cock the weapon. The Mk 19 is able to launch its grenade at a maximum distance of 2,212 meters, though its effective range for a point target is about 1,500 meters, since the large rear leaf sight is only graduated to 1,500 meters. The nearest safe distance to launch the grenade is 310 meters in training and 75 meters in combat. Though the Mk 19 has a flash suppressor, it serves only to save the eyesight of its operator; it does not conceal the weapon's position. For night operation, an AN/TVS-5 night vision sight can be fitted.

AT4

The AT4 (also variously AT-4, AT4 CS, AT4-CS, or AT-4CS) is an 84-mm unguided, portable, single-shot recoilless smoothbore weapon built in Sweden by Saab Bofors Dynamics (previously Bofors Anti-Armour Systems). Saab has had considerable sales success with the AT4, making it one of the most common light anti-tank weapons in the world.

The designation "CS" represents "confined space" referring to the propellant charge being designed to operate effectively within buildings in an urban environment.^[7] It is intended to give infantry units a means to destroy or disable armored vehicles and fortifications, although it is not generally sufficient to defeat a modern main battle tank (MBT). The launcher and projectile are manufactured prepacked and issued as a single unit of ammunition with the launcher discarded after a single use.

Stick with me guys I will try to cover every gun out there with at least 2 a day.

M249 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 automaticfirepower 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.

The M249 is gas operated and air-cooled. It has a quick-change barrel, allowing the gunner to rapidly replace an overheated or jammed barrel. A folding bipod is attached near the front of the gun, though an M192 LGM tripod is also available. It can be fed from both linked ammunition and STANAG magazines, like those used in the M16 and M4. This allows the SAW gunner to use rifleman's magazines as an emergency source of ammunition in the event that he runs out of linked rounds. However, this will often cause malfunctions where the magazine spring has difficulty feeding rounds quickly enough to match the SAW's high cyclic rate.

M240 machine gun

The M240, officially Machine Gun, 7.62mm, M240, is the US military designation for the FN MAG (Mitrailleuse d'Appui Général, meaning General Purpose Machine Gun), a family of belt-fed, gas-operated medium machine guns firing the 7.62×51mm NATO cartridge.


The M240 has been used by the United States Armed Forces since the mid-1980s. It is used extensively by infantry, as well as ground vehicles, watercraft, and aircraft. Despite not being the lightest medium machine gun in service, it is highly regarded for reliability, and its standardization among NATO members is also seen as a major advantage.

M4 carbine

The M4 carbine is a family of firearms tracing its lineage back to earlier carbineversions of the M16 rifle, all based on the original AR-15 rifle designed byEugene Stoner and made by ArmaLite. The M4 is a shorter and lighter variant of the M16A2 assault rifle, with 80% parts commonality.


It is a gas-operated, air-cooled, magazine-fed, selective fire, shoulder-firedweapon with a telescoping stock. A shortened variant of the M16A2 rifle, the M4 has a 14.5 in (370 mm) barrel, allowing its user to better operate in close quarters combat. The M4 has selective fire options including semi-automaticand three-round burst (like the M16A2 and M16A4), while the M4A1 has the capability to fire fully automatic instead of three-round burst (like the M16A1 and M16A3). The carbine is also capable of mounting an M203 grenade launcher(the M203A1 with a 9-inch barrel as opposed to the standard 12-inch barrel of the M203 used on the M16 series) as well as its successor, the M320 grenade launcher. 


This weapon daddy of all weapons in the rifle area, with the range and firing rate mixed with its weight and size its   
the scalpel of the  U.S military. I know we all want them but the closes you can get is a AR-15.The AR-15 is based on the 7.62 mm AR-10, designed by Eugene Stoner, 

M24 Sniper

The M24 Sniper Weapon System (SWS) is the military and police version of the Remington 700 rifle, M24 being the model name assigned by the United States Army after adoption as their standard sniper rifle in 1988. The M24 is referred to as a "weapons system" because it consists of not only a rifle, but also a detachable telescopic sight and other accessories.

The M24 SWS had the "long-action" bolt version of the Remington 700 receiver because it originally was to use the .30-06 Springfield M72 Match cartridge. Unfortunately it turned out there was an insufficient amount of these rounds in a single lot of manufacture, so the operational requirement changed to use the dimensionally smaller 7.62×51mm NATO M118 Match Grade cartridge. With this is in a trained snipers hands running away is almost impossible.
