Specna Arms RRA SA-P01 PRIME Aster II ETU Brushless

The Specna Arms PRIME series represents the highest level of factory-built airsoft replicas, combining proven solutions from the EDGE™ / EDGE™ 2.0 lines with brand-new internal components and licensed external designs from manufacturers such as Rock River Arms and Daniel Defense. The result is a rifle that offers exceptional performance, precision and durability without the need for additional upgrades.

Unmatched accuracy

PRIME replicas are equipped with a precision 6.02 mm inner barrel, combined with the TDC Magnus™ Hop-Up chamber and Helium™ Flat Hop bucking, ensuring excellent BB stability, consistent trajectory and superior accuracy at long distances.
An additional O-ring is included to increase the resistance of the Hop-Up adjustment wheel, preventing unwanted movement during gameplay.

Aether™ gearbox – next generation design

At the core of the replica is the Aether™ gearbox, engineered for long-term reliability even with stronger springs. Compared to previous designs, it features reinforced stress areas, precision-cut radiuses and inspection windows for pre-cocking, AOE adjustment and spring release.

Internal components include:

• polymer piston with steel teeth
• metal piston head
• steel cylinder with cooling grooves
• double-sealed cylinder head
• metal air-sealed nozzle

CNC steel gears (16:1 ratio) 

8 mm steel bearings (ball + solid)

The rifle also features the ESA 2 quick-change spring system, allowing fast spring replacement without disassembling the gearbox.

Factory-installed Dark Matter™ brushless motor

One of the most groundbreaking features of the PRIME series is the Dark Matter™ brushless motor, installed directly from the factory.

Benefits of brushless technology:

• extremely low power consumption
• up to 5× longer battery life
• instant trigger response
• higher rate of fire
• reduced heat and wear

This allows the use of compact Li-Po batteries, even in limited handguard spaces.
