In order to handle this rifle correctly and effectively, learning every aspect of this weapon is very essential. Therefore, here is some data on the M16S1 rifle.

Characteristics

i) The rifle is light compared to similar weapons used by other Armed forces. It weighs 3.6 kg (8 lbs.) with a fully loaded 30 round box magazine.

ii) The expanding gas, generated when the cartridge is detonated, is used to power the operating parts, which chambers each succeeding round.

iii) The barrel, which becomes hot during firing, is cooled by being exposed to the air. There is no special cooling device.

iv) The ammunition is contained in a metal-box known as a magazine which contains 30 rounds.

v) The rifle is made to fire either single round or multiple rounds when the trigger is held to the rear. When only single rounds are fired, the rifle is said to be operating on the Semi-Automatic mode whilst when more than one round is fired with the squeeze of the trigger, the rifle is said to be operating on the Fully-Automatic mode.
