KWA is proud to announce a brand new, gas blowback bullpup rifle arriving to retailers in 2022. The officially licensed F90 from Lithgow Arms was the product of a four year partnership with both Lithgow Arms and Thales Australia for end use by the Australian Department of Defense.

The KWA F90 GBB features several improvements from the original AUG design including 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 trigger is a two-stage trigger where half a pull will fire one round in semiautomatic and a full squeeze will fire the rifle in full auto. The automatic lockout trigger ("ALO") acts as the rifle's fire selector and consists of pull tab located at the bottom of the trigger which prevents the trigger from fully travelling to automatic fire.

Many features found on the KWA F90 GBB were taken directly from the contracted GBB rifles supplied to Australian Army including the modular stock/receiver to barrel interface with one pin takedown, expansion slot for integrated grenade launcher found in the trigger housing, waffle patterned AUG style magazine, ambidextrous magazine release, mock adjustable gas block and ambi/adjustable ejection port.

Internally, the F90 shares several components with our existing line of GBB products with improvements to the hop up design and bolt carrier.

We are excited to bring this rare bullpup GBB to the airsoft community as a chance to own a firearm replica not offered to the civilian population.

"Finally! I've been waiting for someone to do the latest version of the AUG for a loooong time, and it's finally here! The Australian military F90! It feels like the real steel ( I have a real AUG for comparison) it looks great, and it functions as good as it looks! I can get two full mag's worth of rounds downrange per green gas fill up. Accuracy is pretty good, but I do get some flyers here and there. As I continue to use it, those are becoming less frequent. I heard that KWA may be releasing this later as an AEG, so if GBB isn't for you, there may be an AEG version coming. I will get that one too, because I do prefer AEGs. I am a huge AUG fan, and if you are too, this is a must-buy! I have yet to field it, so all testing so far is back yard only.
