M4 Carbine

If the Desert Eagle is the celebrity of the handgun world, then the M4 Carbine is surely its assault rifle older brother. This is mostly because any American SWAT officers in any film need to be wielding their trusty M4. This is a member of the M16 family, and is mostly used because it is helpfully lightweight. This gun features some impressively clever technology, such as an air-cooling system, selective fire and an option to add a grenade launcher. Since 1994, it has been deployed in many American combat zones, and is the weapon of choice for the US army. As such, it has been used in both Afghanistan and Iraq by army personnel. In recent years its replacement has been planned for, and in 2008 nineteen arms companies were invited to produce prototypes for the US government. The M4 can fire over 700 rounds per minute - using the .223 Remington / 5.56x45mm cartridge.
