Specna Arms SA-P28 PRIME Aster II ETU Daniel Defense RIS III 12.5" AEG Assault Carbine - Black

Electric-powered SA-P28 assault carbine replica from the PRIME series, featuring a 12.5-inch handguard inspired by the Daniel Defense RIS III model with the M-LOK mounting system, equipped with a Specna Arms Dark Matter High Speed 27k brushless motor and a Gate Aster II Bluetooth control unit enabling advanced customization of the replica's settings.

Metal body, Nano Coating

Constructed with a metal body, front grip, outer barrel, and receiver extension of the stock, this replica incorporates steel screws and pins for enhanced durability. The grips—both pistol and vertical—as well as the flask and stock, use robust plastic. An anti-scratch Nano Coating provides a premium finish on the body. Authentic licensed markings from the American firearms manufacturer Daniel Defense are etched onto the replica. Additionally, every unit carries a unique serial number, verified with a hologram for authenticity.

A 22 mm RIS rail located at the rear supports the installation of various optoelectronic sights. Factory-fitted mechanical adjustable flip-up type targeting systems include a front and peep sight. For attaching additional tactical accessories, a Daniel Defense RIS III handguard featuring the M-LOK system and an integrated front grip is used. Adaptable to shooter preferences, the stock is extendable and finished with a recoil pad that offers a non-slip surface for optimal comfort. The set includes two S-MAG-type polymer Mid-Cap magazines with a 125-round capacity.

Precision barrel, rotating Hop-Up chamber

Equipped with a TDC Magnus rotary Hop-Up chamber and a 6.02 mm precision steel barrel, the SA-P28 offers enhanced shooting accuracy out of the box. The outer barrel is finished with a standard flash suppressor mounted on a 14-mm left-hand thread, enabling quick installation of a sound suppressor as an alternative.

Specna Arms Aether Gearbox

At the core of the replica lies a V2 gearbox built upon the robust Specna Arms Aether frame, featuring:

  • a quick-release mainspring mechanism
  • pre-cocking and AoE inspection ports
  • a strengthened front section of the frame
  • inspection ports for convenient arming
  • an adjustable trigger system

Internally, the gearbox utilizes components including:

  • a reinforced polymer piston equipped with a full steel rack
  • aluminum heads for both piston and cylinder
  • a spring guide mounted on bearings
  • a CNC-machined steel gear set with a 16:1 ratio
  • 8 mm J-Cage ball bearings for the motor and piston pinion
  • 8 mm bushings for the center pinion and a Quantum Trigger 2 system
  • a Specna Arms Dark Matter High Speed 27k brushless motor

Dark Matter High Speed 27k brushless motor

The replica comes standard with a premium Dark Matter High Speed 27k brushless motor, delivering increased power, fast rate of fire, enhanced reliability, and superior performance. Engineered for compatibility with extremely strong springs (up to M190), the motor delivers high torque (approximately 27,000 RPM).

The Dark Matter High Speed 27k brushless motor includes the following features :

  • high torque
  • enhanced trigger response and a high TPA rating
  • significantly quieter operation
  • CNC-machined aluminum housing
  • lower power usage and reduced battery strain, resulting in greater performance
  • extended service life and minimized component wear

Gate Aster II Bluetooth control module

The SA-P28 is outfitted with a Gate Aster II Bluetooth control unit paired with a Quantum Trigger 2, enabling comprehensive access to replica configuration and personalization. Compatibility with both brushed and brushless motors is ensured. Featuring a built-in fuse, the Aster II safeguards the battery, gearbox, motor, and electronics. Built in line with military specification MIL-V-173C, robust protection against challenging weather is provided.

Key attributes of the Gate Aster II unit:

  • The Quantum Trigger 2 offers adjustable trigger sensitivity
  • Binary trigger functionality
  • Integrated battery over-discharge protection
  • Pre-cocking feature delivers an enhanced trigger response
  • Active Break system ensures the replica completes a full firing cycle with every shot, preventing gearbox strain caused by incomplete cycles

  • Bluetooth integration for seamless connection with a dedicated mobile app

ESA 2 quick-change spring system

Configured in its standard setup, the replica achieves a firing velocity of 430 FPS.
