M75 Modular Combat Shotgun

The M75 is a pump-action combat shotgun designed by Misriah Armories to replace the M45 Tactical Shotgun in the UNSC Army, issued in 2565 along with the MA6 Series and the M65 LMG. It shares the M45's adjustable stock and tighter pellet spread and accuracy, but has a larger 9-shell ammo capacity.
