The MGL-6 is a six-shot revolver grenade launcher that can fire frag, smoke, poison, EMP or incendiary grenades. The base gun comes from the Parting Gifts treasure hunt.
Six grenades before a reload let you break up a group or wreck several light vehicles in a row. Swap grenade types for the job: poison to turn soldiers on each other, EMP for vehicles, smoke to cover a retreat.
Complete Parting Gifts for the base launcher. Pick up El Caballero at the F.I. Escudo Steel Plant in Aguas Lindas. Beat Cherche Rocha's insurgency for Organ Donor. A Libertad Custom version also exists.
El Caballero adds faster movement while aiming and reloads all your weapons at once. Organ Donor comes with a micro reflex sight. Both have fixed mods and cannot be changed at a workbench.
DShK
The DShK is a heavy machine gun you only fire from a fixed mount or a vehicle. You cannot pick it up, but jumping on one at a checkpoint or using a tank's DShK gives you heavy firepower against troops and vehicles.

The M-79 is a break-action grenade launcher that fires one grenade per load. Its three unique versions come from a treasure hunt and two insurgency fights.
RAT4
