DesertFox Airsoft's "Straight Outta the Box" series feature the KWA Lithgow Arms F90 GBB. The KWA F90 GBB improves upon the AUG design with a shorter length of pull, more picatinny rails, and a folding charging handle. It also boasts a two-stage trigger for semi-auto and full-auto fire, with a fire selector built into the trigger itself. Faithfully replicating features of the Australian Army rifles, the F90 GBB has a one-pin takedown system, space for a grenade launcher, familiar AUG magazines, ambidextrous controls, and an adjustable hop-up and bolt carrier for enhanced performance.
