Specna Arms RRA SA-E05 EDGE™ HAL 2 ETU Light Ops Stock Gen. 2 - Black
The Specna Arms SA-E05 EDGE™ Gen. 2 combines a metal receiver with licensed Rock River Arms markings, the programmable HAL²™ electronic trigger system and a reinforced Æther™ V2 gearbox. Its quad RIS handguard and lightweight Light Ops Stock provide a practical combination of accessory mounting options and compact handling.
The metal receiver features official Rock River Arms markings and an individual serial number. The handguard has RIS rails on all four sides for mounting accessories, while the minimalist Light Ops Stock keeps the rear of the rifle lightweight. Rubberized cheek contact areas and a curved rubber buttpad provide a comfortable fit against the shoulder.
A QD pistol grip allows access to the motor without tools, and ambidextrous sling mounting points make it easier to configure the rifle for different carrying preferences.
HAL²™ ETU and Specna Link™ App
The HAL²™ electronic trigger unit uses magnetic Hall-effect sensing instead of traditional mechanical trigger contacts. It offers a responsive trigger with extensive adjustment options through the Specna Link™ mobile app, which connects to the rifle using Bluetooth® Low Energy.
The app allows you to tailor the rifle's behavior to your preferences and save different settings profiles for different playing situations.
- Trigger sensitivity adjustment with up to 500 setting points
- Adjustable precocking for faster trigger response
- Programmable SEMI, BINARY, BURST and AUTO firing modes
- Adjustable burst length and rate of fire
- LiPo and Li-Ion battery over-discharge protection
- Magazine mode and real-time battery status monitoring
- Saved settings profiles, diagnostics and telemetry
Trigger calibration: The HAL²™ system requires trigger calibration during setup. During the final calibration stage, the trigger should be pulled slowly and smoothly. Pulling it too quickly may cause the calibration to fail.
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 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 without opening or removing the gearbox. Access to the spring guide is provided through the buffer tube, making it easier to adjust muzzle energy to suit different playing field limits.
An additional M90 spring is included for lower-power setups. When using the M90 spring, the manufacturer recommends a 7.4 V battery to help prevent potential operating issues.
