Specna Arms SA-P21 PRIME™ Aster II ETU Brushless – Black

The Specna Arms SA-P21 PRIME™ represents the top tier of Specna Arms airsoft rifles. The PRIME™ series is built on years of experience, innovation and passion for airsoft, combining proven AR15 platforms with cutting-edge internal technology.

PRIME™ is the first mass-produced airsoft rifle series equipped with a factory-installed brushless motor. The Specna Arms Dark Matter™ High Speed 27K brushless motor delivers extremely low power consumption, instant trigger response and high rate of fire with minimal wear.

Construction and accuracy

The metal body features a durable Nano Coating finish that protects against scratches and wear. Each rifle comes with an individual serial number and hologram-verified barrel.
Accuracy is ensured by a 6.02 mm steel inner barrel (210 mm) combined with the Magnus™ TDC rotary hop-up chamber and Helium™ flat hop-up bucking, providing consistent BB trajectory.

ÆTHER™ gearbox and ESA2™

At the core is the reinforced ÆTHER™ V2 gearbox, designed for high durability and heavy springs. It includes inspection windows for AOE, pre-cocking and motor pinion alignment.

The ESA2™ quick-change spring system allows fast power adjustment without tools. The package includes M90 and M135 springs, making the rifle suitable for both CQB and outdoor fields.
