The following weapons were used in the film Avengers: Infinity War:
M249 Paratrooper SAW
Bucky Barnes (Sebastian Stan) is seen armed with what appears to be a M249 SAW Paratooper fitted with a SureFire 100-round casket magazine. This SAW is identical to the one used by Barnes during the climax of Civil War, and may be intended to be the very same weapon.
