Specna Arms Daniel Defense® RIS III 10.5'' SA-E27 EDGE™ HAL 2™ ETU Gen. 2 - Chaos Bronze
The Specna Arms SA-E27 EDGE™ Gen. 2 is an electric airsoft carbine combining licensed Daniel Defense® RIS III externals with a programmable HAL²™ ETU, reinforced Æther™ gearbox and ESA™ quick spring change system. The Chaos Bronze finish gives this M4/AR15 platform a distinctive appearance, while the upgraded internal components and adjustable electronics offer plenty of options for different playing styles.
The carbine features metal receivers, official Daniel Defense® markings and an individual serial number. Its aluminum RIS III handguard has a Nano Coating finish designed to resist scratches. The 10.5-inch handguard combines M-LOK mounting slots with Picatinny rails, allowing accessories such as lights and foregrips to be installed. An enlarged SF-style stock provides space for the battery, while folding sights, an ambidextrous sling attachment point and a pistol grip with tool-free motor access add practicality.
HAL²™ ETU and Specna Link™ App
The HAL²™ electronic trigger unit uses magnetic Hall-effect sensors to detect trigger movement. Its integrated Bluetooth® Low Energy connection allows the user to configure the electronics through the free Specna Link™ smartphone app.
- Adjustable trigger sensitivity for different shooting preferences
- Pre-cocking for faster trigger response
- Programmable SEMI, BINARY, BURST and AUTO firing modes
- Adjustable burst length and rate of fire
- LiPo/Li-Ion battery over-discharge protection
- Battery voltage monitoring and real-time operating information
- Ability to save different settings and profiles
Important information about trigger calibration: Although HAL²™ units are factory-calibrated, trigger recalibration through the Specna Link™ app may be necessary before use. In practice, calibration can be frustrating and may require several attempts, even when following the instructions. During the final calibration step, the trigger must be pulled slowly and smoothly. Pulling it too quickly can cause calibration to fail. Allow some time for the initial setup.
Motor compatibility: HAL²™ does not support brushless DC (BLDC) motors.
Hop-Up and Internal Components
The 6.03 mm precision inner barrel works together with the MAGNUS TDC rotary hop-up chamber and HELIUM™ Flat Hop bucking. The centrally applied TDC adjustment helps achieve consistent BB hop and allows the player to fine-tune the trajectory.
The reinforced Æther™ V2 gearbox features steel gears, a sealed aluminum nozzle and a polymer piston with a full steel tooth rack. Its reinforced shell also includes inspection openings for easier maintenance and adjustment of internal components.
- 6.03 mm precision inner barrel
- MAGNUS TDC adjustable hop-up chamber
- HELIUM™ Flat Hop bucking
- Reinforced Æther™ V2 gearbox shell
- Steel gears and polymer piston with full steel tooth rack
- Sealed aluminum nozzle
- Aluminum cylinder and double-sealed aluminum cylinder head

ESA™ Quick Spring Change System
The ESA™ system allows the main spring to be changed through the buffer tube without removing or opening the gearbox. This makes it easier to adjust the carbine's power to different field limits. An additional M90 spring is included in the package.
Battery recommendation: When using the M90 spring, a 7.4 V battery is recommended to avoid potential malfunctions.
