Specna Arms Daniel Defense® MK18 SA-E19 EDGE™ HAL 2 ETU Gen. 2 - Black
The Specna Arms Daniel Defense® MK18 SA-E19 EDGE™ Gen. 2 is a compact, metal-bodied electric airsoft carbine featuring official Daniel Defense® markings, a programmable HAL²™ ETU and upgraded internals. Its reinforced Æther™ gearbox, MAGNUS TDC hop-up and ESA™ quick spring change system make it a versatile choice for different airsoft playing environments.
Manufactured by Specna Arms in cooperation with EMG Arms, the SA-E19 features licensed Daniel Defense® MK18 markings and a distinctive RIS II handguard with Picatinny rails for mounting grips, lights and other compatible accessories. The metal receiver has a scratch-resistant Nano Coating, while the adjustable stock provides space for the battery. Folding sights, a full-length upper rail and a vertical foregrip complete the MK18 configuration.
HAL²™ ETU and Specna Link™ App
The HAL²™ electronic trigger unit uses magnetic Hall effect sensors to detect trigger movement. It offers adjustable trigger sensitivity and programmable firing modes without conventional mechanical trigger contacts. Its built-in Bluetooth® Low Energy connection allows settings to be adjusted through the free Specna Link™ smartphone app.
The Specna Link™ app provides access to the following features:
- Trigger sensitivity adjustment with up to 500 sensitivity points
- Adjustable 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
- Magazine mode and battery charge monitoring
- Saved setting profiles for different playing environments
- Real-time status monitoring and diagnostic data
Important information about trigger calibration: The HAL²™ trigger may require calibration through the Specna Link™ app before first use. In practice, calibration can be frustrating and may take several attempts to complete successfully. 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: The HAL²™ ETU does not support brushless DC motors (BLDC).
Hop-Up and Internal Components
The 6.03 mm precision inner barrel works together with the MAGNUS TDC hop-up chamber and HELIUM™ Flat Hop bucking. The centered TDC adjustment helps provide consistent hop-up pressure and allows fine-tuning of the BB's flight path.
The reinforced Æther™ V2 gearbox contains steel gears, a sealed aluminum nozzle and a polymer piston with a full steel tooth rack. Its shell features reinforcements in high-stress areas and inspection windows that make maintenance and internal adjustments easier.

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