SA-F14 FLEX Gen.2 HAL ETU Half-Tan Airsoft rifle

SA-F14 FLEX Gen.2 HAL ETU Half-Tan Airsoft rifle is Specna Arms’ high-performance carbine engineered for players who demand precision, reliability, and field-ready versatility. Built around the proven FLEX platform, this Gen.2 model enhancements deliver smoother handling, easier tuning, and repeatable accuracy—right out of the box.

The HAL ETU system sits at the heart of this replica, delivering intelligent fire control with magnetic-sensor triggering, active braking, and highly tunable fire modes. Combined with the Æther™ gearbox and a reinforced frame, the SA-F14 FLEX Gen.2 HAL ETU is designed to perform under pressure—whether you’re sprinting CQB lanes or engaging from longer sightlines on outdoor fields.

Key hardware highlights include a rotating TDC Magnus™ Hop-Up chamber for precise, repeatable elevation, the Helium™ Flat Hop Eraser for stable backspin, and a sealed aluminum nozzle for consistent air seal. The core internals feature 8mm plain bearings, steel gears, and a polycarbonate piston with full steel slats, all housed in a lightweight nylon fibre-reinforced polymer chassis with essential metal components for durability where it counts.

HAL ETU System: precision, customization, and programmable fire

• Trigger sensing and control via magnetic sensors and Hall effect for ultra-fast response and repeatable actuation.
• Active brake and a binary trigger option deliver crisp trigger feel and predictable follow-up shots.
• Five selectable trigger sensitivity levels (20–100%) plus six pre-cocking settings to tailor responsiveness to your play style.
• AUTO programmable fire modes (full auto, semi, 3-round burst, 5-round burst) and sEMI programmable modes (semi, binary, AUG, sniper) for rapid adaptation to different game formats.
• Low-battery alarm and brushless-motor compatibility for modern, high-torque builds.
• Automatic 3-round burst before Full Auto in AUTO mode to balance ammo management with continuous firepower.

Durable construction designed for tough field use

The SA-F14 FLEX Gen.2 HAL ETU uses a robust nylon fibre-reinforced polymer chassis with strategic metal components (flame suppressor, external barrel, dummy slide, shell ejector flap, fire mode switch, breech release, magazine clip, QD attachments, pins, and reloading lever). This blend delivers a light, rigid platform capable of withstanding the rigors of regular play while maintaining a low weight for fast maneuvers. The Light Ops Stock features rubberized, non-slip cheek areas and a curved stock foot that sits securely against the shoulder for stable aiming under motion.

Internals and performance you can feel

• eSA™ quick-change spring system enables rapid field adjustments to power output (no tools required beyond field-accessible steps), letting you tune for indoor, outdoor, or woodland environments.
• Æther™ Gearbox shell paired with reinforced frame ensures consistent engagement of gears and tappet, contributing to reliable cycling with M140-class springs.
• 8mm plain bearings and steel gears provide smooth, durable operation while the precision 6.03mm barrel supports tight shot grouping at typical airsoft distances.

What’s in the box

The package includes a reliable S-Mag Hi-Cap magazine to support sustained firing on the field, along with the essential hardware to keep you field-ready. The rifle’s modular layout also accommodates front sighting options via the M-LOK standard and folding sighting instruments for quick engagement at close quarters.
