Jatimatic
That one gun in CobraA stockless Finnish SMG with a foregrip that triples as a charging handle and safety. Never saw commercial success, with its sole major on-screen presence in the 1986 Stallone film Cobra.
Push up on the touchpad (B/Y on Streamlined) to toggle the safety, and down on the touchpad (A/X on Streamlined) to unlock the foregrip for cocking the bolt back.
