M4 Airsoft SA-E22 EDGE HAL 2 ETU V2
Specna Arms SA-E22 EDGE™ HAL² ETU Gen. 2 — Airsoft Carbine
Factory-ready EDGE™ performance with a pro-level electronic brain. The SA-E22 EDGE™ HAL² ETU Gen. 2 blends Specna Arms’ reinforced AETHER™ platform with the HAL²™ Hall-effect electronic trigger — delivering razor-sharp trigger feel, app-enabled tuning, and field-friendly serviceability straight out of the box. Built for CQB, milsim and weekend skirmishes, this carbine gives you competitive accuracy, instant trigger response and easy power tuning via the ESA quick-spring system.
Why players choose the SA-E22
- Ultra-responsive HAL²™ ETU: Hall-effect trigger (500+ sensitivity points) with built-in Bluetooth® Low Energy — program trigger sensitivity, pre-cocking, fire modes (SEMI, BINARY, BURST, AUTO) and monitor battery/telemetry via the free Specna Link™ app.
- Field-upgradeable & protected: ÆTHER™ reinforced gearbox shell (EU patent) with inspection windows, anti-reversal, AoE and motor pinion windows and trigger adjustment — tough and serviceable under pressure.
- Precision internals: 6.03 mm tight bore precision barrel paired with the MAGNUS™ TDC rotating hop-up chamber and Helium™ Flat Hop Eraser for consistent grouping and stable BB flight.
- Quick spring changes: ESA™ quick-change spring system lets you drop or swap power springs in minutes — ideal for switching between field limits (outdoor → CQB) without a full disassembly.
- Robust construction: Metal majority components with polymer folding sights, QD polymer pistol grip and adjustable polymer stock for a balanced, durable build.
Performance & on-field benefits
Reliable trigger control: HAL²’s Hall sensor avoids false-triggers caused by dirt or light, giving you crisp single shots, clean binary bursts, or tuned full auto with adjustable burst length and ROF.
Accuracy where it counts: The 6.03mm precision barrel + Magnus TDC hop-up combination improves consistency at medium ranges and makes this carbine a capable skirmish and support platform for objective play.
Fast tuning for different gametypes: Want lower FPS for indoor CQB or higher power for woodland fields? ESA™ quick spring change and the included spare M90 spring let you adapt quickly between matches.
Ergonomics & accessory options
- M-LOK front handguard for lights, grips, laser modules and offset sights.
- RIS top rail and folding sights — ready for any optic or red-dot.
- QD pistol grip for tool-less motor access and a double-sided sling attachment point for fast transitions.
- 14mm CCW threaded outer barrel — accepts standard airsoft suppressors and mock compensators.
What’s in the box
- Specna Arms SA-E22 EDGE™ HAL² ETU Gen. 2 replica
- 2 × mid-cap S-MAG magazines (approx. 125rd capacity)
- M90 additional spring
- Angled forward grip & cleaning rod
- Small Tamiya → DEANS adapter, BBs speedloader
Note: Battery and charger are not included. This AEG uses a DEANS / T-connector — choose quality LiPo/Li-Ion packs. See /collections/batteries-and-chargers for compatible options.
Ideal user
Perfect for skirmishers who want a drop-in high-functioning carbine with electronic tuning, and for teams that benefit from telemetry and saved profiles (multiple shooter profiles can be stored in the Specna Link™ app). If you value crisp trigger response, easy on-field power changes, and a durable, modular platform — the SA-E22 is built for you.
