Description
Specna Arms SA-PH20 PRIME™ ASTER II™ ETU airsoft Carbine with Brushless Motor Black
The Specna Arms SA-PH20 PRIME™ ASTER II™ ETU Airsoft Carbine with Brushless Motor in Black delivers top-tier performance straight out of the box. Designed for serious airsoft players, this high-spec carbine integrates advanced internal systems with robust external construction, making it ideal for both competitive and tactical use.
Specna Arms PRIME™ series represents a new generation of airsoft rifles, combining EDGE™, EDGE 2.0™, and H Series innovation with the latest brushless motor technology. The result is a weapon system engineered for speed, responsiveness, and long-term reliability—without requiring additional upgrades.
A key innovation lies in the Specna Arms Dark Matter™ 27k Brushless Motor, which provides superior torque and efficiency due to reduced internal resistance. In turn, this enables faster trigger response and increased cycle rate, making each shot smoother and more consistent.
Another defining element is the newly developed Æther™ Gearbox, which reinforces structural integrity and supports M140 spring compatibility. Together with the HAL™ ETU and patented ESA2™ quick-change spring system, players can easily adapt power output to site limits or specific engagement ranges—without opening the gearbox.
