SA x KPYK AK-74S (SA-PJ13 PRIME™) ASTER V3™ BLDC™ – Black

Specna Arms PRIME™ AK-74S with Genuine KPYK® Accessories

The AK-74S PRIME™ from Specna Arms x KPYK® is one of the best-equipped airsoft AK platforms on the market. It combines a PRIME™ series steel receiver, premium internal components and genuine external accessories from the Ukrainian company KPYK® (KRUK), originally designed for real firearms. The result is a rifle with maximum realism, excellent durability and top-tier performance straight out of the box. Thanks to the KPYK® CRC 1U020 aluminum M-LOK handguard, top RIS rail and folding skeleton stock, you get a modern AK setup ready for both CQB and outdoor gameplay. The manufacturer also used a low-profile MAGNUS™ TDC hop-up chamber, allowing enough space under the dust cover for a TITAN 11.1V 3000 mAh Stick Li-Ion battery, which we highly recommend for this rifle. On the side, you will also find a Dovetail mounting rail compatible with AK/SVD side mounts. This professional product description was prepared by the expert team at ANAREUS.cz.

Key Product Features

BLDC™ Internal Parts and GATE ASTER V3 ETU

Inside the rifle, you will find a reinforced V3 gearbox equipped with premium upgrade parts ready for demanding use. At the heart of the setup is the Dark Matter™ brushless motor with switchable speeds of 27,000-35,000 RPM, providing instant trigger response, higher rate of fire and lower energy consumption. Power transfer is handled by 16:1 CNC steel gears, a reinforced polycarbonate piston with 14 steel teeth and a combination of ball bearings and bushings for the ideal balance of speed and durability. Accuracy is enhanced by a 6.02 mm precision inner barrel together with a Helium Flat-Hop bucking and the MAGNUS™ TDC chamber. The GATE ASTER V3 ETU allows advanced rifle configuration including pre-cocking, binary trigger and DMR mode. Thanks to the ESA2 QSC system, you can also change the spring within minutes without disassembling the gearbox.

Warnings

• Springs from some manufacturers are significantly overpowered (e.g., an M130 may perform like an M140–150), which may exceed the declared gearbox durability. We recommend using only the included Specna Arms springs. If using springs from other brands, choose M120-class springs to avoid potential damage.
• If installing a spring with progressive (irregular) winding, make sure the tighter coil end faces outward toward the spring guide.
• Never store the rifle with the battery connected.
• Never store the rifle with the piston pre-cocked (pre-cocking mode active). Always release the piston before storage to avoid spring damage.
