SA-F14 FLEX™ Gen.2 HAL ETU™ - Olive

The Specna Arms SA-F14 FLEX™ Gen.2 HAL ETU™ is an electric airsoft carbine designed for players looking for a strong balance of price, performance, and modern features. The second generation of the FLEX™ series brings an updated design, improved internals, and functions usually found in more expensive replicas.

The replica is made primarily from nylon fiber reinforced polymer, which keeps the weight low while maintaining good durability. Stress-bearing external parts such as the flash hider, outer barrel, fire selector, charging handle, and pins are made of metal. The result is a lightweight yet solid carbine suitable for both newer and more experienced players.

Reinforced Æther™ gearbox – built for durability

Inside you’ll find the reinforced Æther™ gearbox, designed for higher stress and long-term use.

Key points:

• reinforced shell in critical areas,

• inspection windows for checking AoE and spring preload,

• window for easier motor pinion adjustment,

• trigger adjustment function in combination with HAL²™.

Internal / air-seal parts:

• polymer piston with full steel rack,

• bearing spring guide,

• sealed polymer piston head with bearing,

• aluminium cylinder,

• double-sealed aluminium cylinder head,

• sealed aluminium nozzle,

• steel gear set.

All this gives you stable performance, good air seal and lower risk of damage even under heavy use.

Precision barrel and modern hop-up

To keep shots consistent and accurate, the SA-E22 comes with:

• a 6.03 mm precision inner barrel (approx. 375 mm),

• a rotary TDC Magnus hop-up unit for fine and repeatable adjustment,

• a Helium™ flat hop nub / bucking, which stabilises the BB’s backspin.

For you as a player, this means straighter trajectories and more consistent hits, especially at medium to longer ranges.

Smart HAL™

The heart of this rifle is the HAL™ system, which uses a magnetic Hall sensor on the trigger. This allows extremely fine trigger adjustment (hundreds of sensitivity points), and at the same time is resistant to dust and light.

In the app you can:

• adjust trigger sensitivity – from a longer pull to an ultra-short “click”,

• enable pre-cocking for faster shot response,

• choose fire modes – SINGLE, BINARY, BURST (SERIAL) or FULL AUTO and assign them to selector positions,

• set burst length (number of shots),

• adjust rate of fire (ROF),

• enable LiPo / Li-Ion low-voltage protection,

• use magazine mode (simulation of an empty magazine),

• monitor battery level and telemetry data (performance over time),

• save different profiles for various game styles or for multiple replicas.

Just connect and you have full control over how your replica behaves – no tech bench needed.

ESA™ quick spring change system

The rifle features the ESA™ quick spring change system.

What that means in practice:

• you don’t need to open the entire gearbox,

• you remove the spring guide and swap the main spring,

• you can easily adjust FPS to different field limits (outdoor / CQB).

In the box you also get an extra M90 spring, useful when you need to lower the power for stricter fields or indoor games.

The rifle is equipped with an M-LOK handguard, folding sights, and the lightweight Light Ops Stock, offering a modern look and comfortable shoulder placement. It is ready for 11.1V LiPo batteries and uses a DEANS / T-connect plug.
Battery and charger are not included.

Important notice:
When starting the replica for the first time after connecting the battery, hold the trigger in SAFE mode for about 5 seconds to activate the HAL™ module.
