SA-FX01 FLEX™ HAL ETU Gen.2 - Olive

The Specna Arms FLEX™ Gen.2 carbine line was redesigned to offer the best possible user experience at an attractive price. It’s built to be field-ready straight from the box, focusing on consistency, durability, and smart electronic features.

Accuracy & consistency

The replica features the TDC Magnus™ Rotary Hop-Up Chamber (Top Down Center) for very precise and stable hop-up adjustment, supported by the Helium™ Flat Hop Eraser to improve BB flight stability. Internally you’ll also find a 6.03 mm precision barrel, a sealed aluminum nozzle, steel gears, 8 mm bearings, and a polycarbonate piston with full steel rack.

Reinforced Æther™ gearbox & quick spring change

At the core is the Æther™ Gearbox reinforced shell with practical features:

• mainspring release

• pre-cocking & AoE inspection windows

• reinforced front

• inspection windows for easier servicing/priming checks

• trigger adjustment function

• alignment screw holes for better frame fit

• ready for M140 springs

The ESA™ quick spring change system lets you adapt power to field limits quickly without a workshop or specialized tools. An extra M90 spring is included.

HAL™ ETU Gen.2 – advanced electronics

The HAL™ electronic trigger unit provides fast response and deep customization:

• magnetic trigger detection (Hall effect sensors)

• active brake

• binary trigger

• adjustable trigger sensitivity (5 levels, 20–100%)

• adjustable pre-cocking (6 levels)

• programmable AUTO modes (full auto / semi / 3-rd burst / 5-rd burst)

• programmable SEMI modes (semi / binary / AUG / sniper)

• easy trigger-based programming

• low battery alarm

• brushless motor compatible

Note: AUTO fires a 3-round burst first, then switches to Full Auto.

Build & ergonomics

The body and front end use nylon fibre-reinforced polymer, reducing weight and making it excellent for dynamic CQB, while remaining more robust than standard polymer builds. Fitment is tight with no noticeable wobble between upper and lower parts. Metal elements add durability where needed, and pins/smaller parts are made of steel.

The Light Ops Stock is a minimalist, modern and lightweight stock featuring non-slip rubber cheek stickers and a comfortable rubber buttpad.
