Available now at Evike.com is the KWA Lithgow F90 GBB and they did a review of this bullpup airsoft rifle. KWA, in collaboration with Lithgow Arms and Thales Australia, is excited to introduce the F90, a gas blowback bullpup rifle, set to hit retailers in 2022. This officially licensed product, designed for the Australian Department of Defense, boasts several enhancements from the original AUG design, such as a shortened length of pull, extended top picatinny rail, additional picatinny space at the 3-6 o'clock positions, and a folding, non-reciprocating charging handle. The F90's two-stage trigger allows for semi-automatic fire with half a pull and full auto with a full squeeze, while the automatic lockout trigger acts as the fire selector.

The rifle also features a modular stock/receiver to barrel interface with one pin takedown, an expansion slot for an integrated grenade launcher, a waffle patterned AUG style magazine, an ambidextrous magazine release, a mock adjustable gas block, and an adjustable ejection port. Internally, the F90 shares several components with KWA's existing line of GBB products, with improvements to the hop up design and bolt carrier.
