MA5K carbine

The MA5K Assault Rifle is a United Nations Space Command infantry-sized projectile firearm.

Design
It is a cut-down version of the MA5B Assault Rifle. The weapon is most likely lighter and easy to carry than larger assault weapons. It featured stripped down features that appeared almost skeletal.

Based on current-era tactical philosophy, it is believed that the MA5K variant was produced specifically for Special Operations forces because of its lighter frame, which allowed for more quick manuevering and less visible profile, and probably for its lighter aural signature, which suits the requirements of commando missions.

Usage
MA5Ks were not as often used for frontline duty because of their reduced stopping power, but they came into use by the Spartan-IIIs from 2531 to 2552
