"This is an accomplished AK replica, both realistic and effective. The collaboration with KPYK has resulted in a very modern AK. Its modularity clearly makes the difference, both externally and internally. Whatever the terrain or style of play required, adaptation is immediate via the application or a quick spring change."

The AEG SA-PJ15 PRIME Aster ETU BLDC Carbine airsoft replica is the result of a collaboration between Specna Arms and KPYK. KPYK is a Ukrainian company specializing in modern accessories, with a particular focus on the AK system, and a philosophy that combines durability, design and functionality, so that each element brings a concrete benefit to its user. Thanks to this partnership, Specna Arms declines its Prime™ J-Series range, an evolution of the J-Series Edge 2.0™ enriched with new internal parts and technical elements designed to deliver excellent performance and durability right out of the box. This "ready for action" logic is supported in particular by the integration of the Specna Arms Magnus™ hop-up chamber with TDC adjustment, designed for a stable and precise fit.
The SA-PJ15 PRIME features an overwhelmingly steel construction, with steel components advertised as the barrel, dust cover, outer barrel, trigger guard, mag release, selector, strap attachment point, gas tube as well as various structural elements. Aluminum is used on key parts such as the sights, the muzzle device, the moving part with the cocking lever, the stock guides, and above all the KPYK CRC 1U020 handguard, one of the signature elements of this configuration. The whole system has been designed to offer modern ergonomics and excellent modularity, thanks to M-LOK interfaces and a Picatinny rail that makes it easy to add a sighting optic, light, laser or vertical grip. The pistol grip, adjustable tactical stock and mid-cap magazines are made of polymer, to maintain an effective grip and limit the weight on handling components.
The external finish features Nano Coating to limit marks and scratches. The black metal flame arrestor is mounted on a 24 mm CW thread. The SA-PJ15 has also been designed for practicality in regular use, with a battery compartment beneath the dust cover offering ample space for a LiPo stick battery. The replica adopts an adjustable tactical stock, and power changes are facilitated by an ESA2 quick-change spring system, designed to simplify access to the spring guide.
Internally, the SA-PJ15 PRIME features a reinforced internal to ensure long-lasting performance. The central pinion is fitted with 8 mm bearings, a steel cylinder, a set of 16:1 steel CNC gears, and a reinforced steel-toothed piston, designed to withstand intensive use and high responsiveness. Precision is ensured by a 6.02 mm barrel, complemented by the Magnus™ TDC rotating hop-up chamber and Helium™ Flat Hop joint, aimed at improving ball stability and trajectory consistency. The heads and nozzle are announced to be made of aluminum, and the replica comes with two additional springs M90 and M135, to adapt power to different terrains or game formats.
Firing rate is entrusted to the Specna Arms DarkMatter™ High Speed 27K brushless motor, while electronic management relies on the GATE ASTER II in Bluetooth 5.2. These electronics provide access to settings, telemetry and advanced functions such as adjustable active brake, pre-cocking (with the option of de-cocking to preserve springs and gears), sniper mode, low battery warning, improved cycle detection and additional protection via multilayer PCB with EMC shielding. Advanced settings and firmware updates are accessible via the GCS app on iOS and Android, with free online updates, and the option of using a mechanical trigger lock is also provided.
The replica comes with a complete package including 2 S-MAG 175 bbs mid-cap magazines, a mini-Tamiya to Deans adapter, a speedloader, a cleaning rod, as well as M90 and M135 springs.
The SA-PJ15 PRIME is aimed at players who want a modernized, ergonomic AK-type replica, with a KPYK signature external and a Prime internal designed to deliver high responsiveness and excellent accuracy.
