M250 light machine gun

The M250 light machine gun is a squad automatic weapon employed by the UNSC Marine Corps and Army. It is essentially a scaled down M247 general purpose machine gun chambered in the same 6.8x43mm round as the M55 SCAR, simplifying logistics at squad level.

Overview
The M250 is a select-fire, gas-operated firearm with a cyclic fire rate of 800 rounds per minute. It can feed from either a 200-round linked belt or a 75-round drum magazine. Switching between belt or magazine feeding is relatively simple thanks to the weapon's modular receiver assembly.
