The Assault Rifle Mk II is the upgraded Assault Rifle in GTA 5 and GTA Online, added with the Gunrunning update and converted at a Weapon Workshop for $98,750. The data lists 40 damage, a fire rate of about 380 rounds per minute, a range figure of 120 and a 30 round magazine. That 40 is the highest damage figure of any assault rifle here. The base Assault Rifle is the weakest rifle per shot in the class, so the Mk II is a big jump. It keeps the slow, controllable 380 rounds per minute rate but hits much harder, which makes it one of the strongest rifles for headshots and NPC work. Special ammo adds Armor Piercing, Incendiary, Tracer and Full Metal Jacket rounds, with Armor Piercing the pick for missions full of armored enemies. Mk II sights, grips, muzzle attachments and camo finishes complete the package. Its fire rate is slower than the Carbine Rifle Mk II, so it feels heavier and less forgiving when you miss. Players who aim well tend to prefer it, and players who spray tend to prefer the Carbine.
Buy it from any Ammu-Nation for $98,750.
