The Combat MG Mk II is the upgraded Combat MG in GTA 5 and GTA Online, added with the Gunrunning update and converted at a Weapon Workshop for $119,000. The data lists 47 damage, a fire rate of about 556 rounds per minute, a range figure of 120 and a 100 round magazine. That is the highest damage of any machine gun here. The base Combat MG is already a favorite for missions because of its big magazine and quick fire rate, and the Mk II adds damage on top. With Armor Piercing rounds it shreds armored NPCs, with Incendiary rounds it sets everything it touches on fire, and Tracer and Full Metal Jacket rounds fill out the list. A hundred rounds before a reload means you can hold a doorway or a rooftop for a long time. The cost is handling. Machine guns are slow to raise and slow to reload, and the Combat MG Mk II feels heavy on screen. It is the wrong gun for a quick freemode duel but the right gun for a long firefight. The plain Combat MG remains a cheap option if the special ammo does not matter to you.
Buy it from any Ammu-Nation for $119,000.
