The M249 is a light machine gun, labeled Tacticool in game, with one of the highest fire rates you can get. It is sold only through Lola's Black Market or the online store.
It mows down crowds up close and stays useful at range once you tame the recoil. The MG42 fires faster and holds more, but the M249 is easier to control and better for long gunfights.
Buy it at Lola's Black Market for Moneda when it is in stock, or purchase it from the online store.
Fit a compensator first to handle recoil. It takes standard, armor-piercing, soft-target, poison, blast and incendiary rounds. You carry 200 rounds, or 400 with a larger ammo pocket.
BP-SMG
The BP-SMG is a compact submachine gun that sprays quickly from a 30-round magazine. It is a good close-range stealth gun with a suppressor, and its unique Iron Curtain fires soft-target rounds.
BZ19
The BZ19 is a submachine gun with a huge helical magazine of 64 rounds. You can hold the trigger far longer than with any other SMG, and its unique Turn Of The Century sits at Resplandor Agriculture in Lozanía.
