Specna Arms SA-P20 PRIME Aster II ETU BLDC AEG rifle

The Specna Arms SA-P20 belongs to the manufacturer's flagship PRIME series and represents the high-performance end of modern AR15-style AEG rifles. The PRIME series combines the proven foundation of the EDGE™ lineup with upgraded internal components, the redesigned Æther™ gearbox, and advanced electronics. The result is a rifle that delivers outstanding performance and extensive tuning capabilities straight out of the box.

The SA-P20 is based on a compact AR15 carbine platform. Its shorter overall length makes it an excellent choice for CQB environments as well as fast-paced outdoor gameplay. The M-LOK handguard provides ample space for accessories, while the top Picatinny rail allows the installation of a wide range of optics and sighting systems. The receiver features a Nano Coating finish designed to improve resistance against scratches during use. Each rifle is also equipped with a unique serial number.

One of the standout features of this PRIME-series rifle is the Specna Arms Dark Matter™ High Speed BLDC brushless motor. Compared to traditional brushed motors, a brushless motor offers faster trigger response, higher efficiency, reduced heat generation, quieter operation, and a longer service life. The motor also delivers high torque from low RPMs and is capable of handling stronger springs without significant performance loss.

At the heart of the rifle is the Specna Arms Æther™ Gearbox, featuring a reinforced shell, spring release function, pre-cocking and AoE inspection windows, and an adjustable trigger system. Internal components include CNC-machined 16:1 steel gears, a full steel-tooth piston, steel cylinder, aluminum nozzle and cylinder head assembly, and an 8 mm bearing setup.

The rifle utilizes the Magnus™ TDC hop-up chamber together with a Helium™ Flat Hop bucking. This combination provides highly precise adjustment and consistent BB flight. Electronics are handled by the Gate ASTER II Bluetooth® ETU, offering trigger programming, active braking, pre-cocking, binary trigger functionality, and Bluetooth connectivity through the GCS application.

The rifle uses a stick-type battery with a Deans (T-plug) connector, installed inside the buffer tube.
