MAC-10

Run at full speed while shooting — the MAC-10's moving accuracy at close range is the whole point of the gun.

Aim upper-chest and let the climb take you to the head; at 800 RPM the headshot finds itself.

Buy it after pistol-round wins: $600 per kill against an eco can bank an extra $1,800–$3,000 for the team.

Force the fight close — smoke or flash your way into 10-metre range where armor penetration stops mattering.

With 100 reserve rounds, don't be shy about pre-spraying corners on entries.

Drop it for any rifle on the ground once the anti-eco job is done — its value ends when helmets arrive.
