KWA F90 GBBR Gas Blowback Rifle - Licensed Lithgow Arms Bullpup

Introducing the KWA F90 GBBR Gas Blowback Rifle, a true gem in the world of airsoft. This officially licensed replica of the Lithgow Arms F90 is the result of a four-year partnership between KWA, Lithgow Arms, and Thales Australia, initially designed for the Australian Department of Defense. With a compact bullpup design, high-quality construction, and a range of remarkable features, this rifle is a game-changer for airsoft enthusiasts.

Experience the ultimate realism with a lightweight polymer stock and full metal upper receiver assembly. The F90 boasts an extended top Picatinny rail and additional rail space at the 3-6 o'clock positions, offering customization options galore. The two-stage trigger provides versatility, allowing both semi-automatic and full-auto firing modes, while the automatic lockout trigger ("ALO") ensures safety and control. This rifle draws inspiration from contracted GBB rifles supplied to the Australian Army, featuring a modular stock-to-barrel interface, an integrated grenade launcher expansion slot, ambidextrous magazine release, and more.

KWA has enhanced the F90 internally, improving the hop-up design and bolt carrier for superior performance. With a velocity of 380-400 FPS and the capability to operate with Green Gas, this rifle offers the power and precision every airsoft player desires.
