A colloquial term used for the six defining features of an assault rifle in the AWB that are intended to differentiate a military firearm from one for sporting or other purposes. Assault rifles are defined as having a detachable magazine and any two of the other features.
- Flash hider – A device that conceals the flash from the muzzle at discharge and helps to hide the shooter.
- Bayonet lug – A device for attaching a bayonet to the rifle.
- Grenade launcher attachment – Rails for mounting a grenade launcher.
- Detachable magazine – A magazine that can be detached from the weapon and allows rapid reloading of cartridges.
- Pistol Grip – A grip that extends down from a standard rifle buttstock and resembles the grip of a handgun. It is designed to provide greater control during rapid fire shooting.
- Folding/telescoping stock – Replaces the standard rifle buttstock with a metal one, hinged to the gun, so that it can be swung 180 degrees forward to become flush with the gun. Modern variants telescope to reduce their length. This device was pioneered by airborne troops to take up less space during transport and generally makes the weapon smaller and more concealable.
