MA3 Assault Rifle

Not to be confused with the MA5B ICWS Assault Rifle.

The MA3 Assault Rifle is a predecessor of the MA5B Assault Rifle used by the UNSC Marine Corps. These weapons were obsolete when the MA5B was produced, as the MA5B was capable of being stripped down or reconfigured in different ways for various missions. The MA5B could become an MA2B Assault Rifle when its excess components were removed.

As of 2552, these weapons were in the black market. Notably, they were used by the Eridanus Rebels for security of Eridanus Secundus.
