Guns, Weapons & FireArms

The M-4 combat assault rifle first entered Army service in 1997. The rifle is the standard weapon used by some Army units such as the 82nd Airborne Division and special operations units, such as Army Rangers.

With a shortened barrel and collapsible stock, the M-4 is ideal for close quarter marksmanship where light weight and quick action are required. Firing a standard 5.56 millimeter round, the weapon weighs a mere 5.6 lbs. (empty). A revised rear sight allows for better control of the weapon out to the maximum range of the ammunition used. With the PAQ-4 (Infrared Sight) mounted on the forward rail system, the M-4 can be fitted for increased firepower.

The M-4 Carbine can also be fitted with the M-203 40mm grenade launcher. The M-203 is a lightweight, compact, breech loading, pump action, single shot launcher. The launcher consists of a hand guard and sight assembly with an adjustable metallic folding, short-range blade sight assembly, and an aluminum receiver assembly which houses the barrel latch, barrel stop and firing mechanism. The launcher is capable of firing a variety of low velocity 40mm ammunition. The launcher also has a quadrant sight that may be attached to the M-4 carrying handle and is used when precision is required out to the maximum effective range of the weapon. The M-4 in this photograph also has an M-68 close-quarters battle sight mounted on the rear rail and a PAQ-4 infra-red sight on the forward rail.
