"This is a successful and very credible AK replica. Thanks to our association with KPYK, we have an ultra-modern, structured AK replica. Its modularity is a real asset, both externally and internally. No matter what the terrain or my desires, I can adapt it very easily from the application or by quickly changing the spring. "

The SA-PJ18 PRIME Aster ETU BLDC Carbine is the result of a partnership between Specna Arms and KPYK, a Ukrainian company specializing in modern accessories, with a strong focus on AK-type platforms. KPYK 's philosophy is simple and effective: to offer parts that combine solidity, functional design and tangible benefits in use, in order to improve ergonomics and efficiency in the field. Specna Arms is using this collaboration to develop its Prime™ J-Series range, an evolution of the J-Series Edge 2.0™ enriched with new internal components and technical elements designed to deliver very good performance and high durability right out of the box. This approach is notably reinforced by the integration of the Specna Arms Magnus™ hop-up chamber with TDC (Top Down Center) adjustment, designed for an ever more precise fit.
Externally, the SA-PJ18 PRIME boasts a very robust design with a metal base, offering a realistic feel and good resistance to intensive use. Metal structural elements and controls include the outer barrel, chamber dust cover, trigger guard, magazine button, selector, rear strap ring and gas tube. Aluminum is reserved for key parts such as the sights, muzzle device, cocking lever and, above all, the KPYK CRC 1U004 handguard, a true signature feature of this version. Thanks to its M-LOK mounts and top Picatinny rail, the replica is immediately ready to be configured to the player's needs with optics, light, laser or grip. To maintain good balance, certain contact parts such as the pistol grip and magazines are made of polymer. The stock on this model is a 6-position retractable polymer stock, enabling rapid length adjustment to suit the size or type of environment.
The finish features a Nano Coating designed to limit the appearance of marks and scratches. At the end of the barrel is a black metallic flame arrestor mounted on a 24 mm CW thread. For everyday practicality, the battery compartment is positioned beneath the dust cover, with space provided for a LiPo stick battery, which remains consistent with AK architecture. Finally, the ESA2™ quick-change spring system makes it easier to adapt power to the rules of the terrain, by simplifying access to the spring guide without having to completely disassemble the gearbox.
inside, the SA-PJ18 highlights a reinforced base designed to maintain stable performance over time. It features 8 mm bearings, a steel cylinder, a 16:1 steel CNC gear set, and a reinforced piston with steel teeth, designed to withstand regular use and high reactivity. Precision relies on the combination of a 6.02 mm barrel, a rotating Magnus™ TDC hop-up chamber and a Helium™ Flat Hop Eraser seal, aimed at stabilizing support and maintaining a clean trajectory, whatever the weights used or playing conditions. The piston heads and nozzle are made of aluminum, and the replica comes with two additional M90 and M135 springs, to allow for power adjustment according to terrain or game formats.
Cadence and responsiveness are entrusted to the Specna Arms DarkMatter™ High Speed 27K brushless motor, while electronic management is based on an integrated Bluetooth MOSFET / ETU GATE ASTER II, designed to improve trigger response and secure the whole assembly. Advanced functions include improved trigger detection, automatic pre-cocking, sensitivity adjustments, more precise cycle detection, configurable active brake, reverse polarity protection and the ability to program certain functions via the trigger. Advanced settings, diagnostics and updates are accessible via USB-Link or Blu-Link and the GCS app available on Android and iOS. The replica comes with two 175-bead polymer mid-cap magazines and T-Deans connectivity, along with a mini-Tamiya adapter.
All in all, the SA-PJ18 PRIME is aimed at players who want a modernized AK replica that's reliable and performs right out of the box, with ergonomics and styling marked by KPYK, Tamiya and Tamiya elements.s by KPYK elements, and a Prime internals designed to keep up with the pace of play without requiring immediate upgrades.
