Ultra-Realistic Licensed Construction

This F90 replica is officially licensed by Lithgow Arms, giving it true-to-form detailing, proportions, and markings.

Enhanced AUG-Inspired Operating System

The KWA F90 retains and improves upon the iconic elements of the AUG family of rifles:

Two-Stage Trigger System

Instead of a traditional fire selector, the F90 uses a signature two-stage trigger:

• Half pull: Semi-auto

• Full pull: Full-auto

The Automatic Lockout Trigger (ALO) provides a safety-style locking mechanism that prevents accidental full-auto fire. This system mirrors real-world operation and offers a unique shooting experience not found on standard M4-based platforms.

Upgraded Ergonomics & Modularity

KWA refined several elements from earlier AUG designs:

• Shortened length of pull

• Extended 1913 Picatinny top rail for modern optics

• 3, 6, and 12 o’clock Picatinny rail segments for lights, grips, and lasers

• Folding, non-reciprocating charging handle

• Improved ambidextrous controls, including mag release and adjustable ejection port

Players get a rifle that feels futuristic, yet highly intuitive and fast to handle.

Improved Performance & Internal Engineering

Internally, the F90 uses KWA’s proven GBB system with upgrades for better consistency and accuracy:

• Enhanced hop-up design for tighter groupings and improved range

• Reinforced bolt carrier

• Shares compatibility with many existing KWA GBB components

• Crisp blowback action for satisfying recoil feedback

With a velocity of 400 FPS, this rifle dominates outdoor fields and MILSIM environments, offering both realism and power straight out of the box.

Authentic Military-Grade Features

Many of the features in the KWA F90 GBB come directly from the real Australian military contract, including:

• Modular receiver-to-barrel interface

• One-pin quick takedown system

• Integrated grenade launcher expansion slot

• Waffle-pattern AUG-style magazine

• Mock adjustable gas block

This rifle isn’t just modeled after a military platform—its design lineage is intertwined with the development of the actual F90 firearm.

A Rare Opportunity for Airsoft Collectors

The real Lithgow F90 is not available to civilian markets, making this licensed gas blowback replica the closest experience possible to owning the genuine rifle. For collectors, historical enthusiasts, and MILSIM players, the KWA F90 represents an exclusive and premium addition to any loadout.
