General Purpose (Hence GP) rifle used by cadets. This is a scaled down version of the British Army's SA80, except the gas parts have been removed, a larger bolt action cocking handle has been fitted and the magazines hold 30 rounds instead of the Army's 25. It uses 5.56mm rounds, and can only be used from the right shoulder.
Can you really think of an example for this? I can't. Ive explained it all up there.
