"Highly modular Australian bullpup assault rifle, chambered in 5.56mm NATO."
— In-game description

The F90 is an assault rifle featured in Tom Clancy's Rainbow Six Siege in the Operation Burnt Horizon expansion pack. It is available for use by Gridlock.


The F90 is an Australian descendent of the AUG A1 design intended for export, licensed by Steyr to Lithgow Arms.

In-game, the F90 features the exact same baseline damage as the G36C but with a slightly steeper damage drop-off. It has below-average damage per shot but makes up for it with an above-average fire rate compared to other Assault Rifles. Thanks to its manageable recoil, the F90 is a solid choice to achieve headshots. Taking only three shots to kill Light and Medium Armored Operators while needing a fourth for Heavy Armored Operators.
