Specna Arms x KPYK SA-PJ12 Prime Aster ETU BLDC AEG Assault Carbine - Half-Tan

An electric replica carbine from the Prime series, inspired by iconic Kalashnikov patterns. Out of the box, the model is fitted with premium components such as: a handguard featuring the CRC 1U004 gas tube cover from KPYK, a Specna Arms Dark Matter High Speed 27-35K brushless motor, and a Gate Aster V3 control unit, offering flexible customization of the replica’s settings to suit individual preferences.

Steel receiver, Nano Coating finish

Constructed predominantly from steel, supplemented by aluminum and plastic elements, the replica features key structural parts crafted from steel, including the receiver, receiver cover, outer barrel, trigger guard, magazine catch, selector lever, tactical sling mount on the buttstock, folding stock, gas tube, and cleaning rod. Components fabricated from aluminum encompass the handguard, sight assemblies, "dovetail" optics mount, bolt carrier with charging handle, and muzzle device. High-strength plastic is utilized for the magazines and pistol grip. The receiver is protected with a Nano Coating finish to increase resistance to scratches.

KPYK CRC 1U004 gas tube cover handguard, folding stock

Factory-fitted with an aluminum handguard and gas tube cover from the Ukrainian company KPYK, the carbine features the CRC 1U004 model in the M-LOK standard, facilitating the mounting of additional tactical accessories. The upper section of the handguard incorporates an additional Picatinny rail. For optics, the carbine utilizes the standard AK mounting system known as “Dovetail”. The SA-PJ13 model is further distinguished by a skeleton stock that folds to the side of the receiver.

Precision barrel, rotary Hop-Up chamber

Equipped straight from the factory, the replica features a rotary Hop-Up TDC Magnus chamber, partnered with a Helium Flat Hop bucking and a 6.02 mm steel precision barrel. The external barrel includes a standard flash hider installed on a 24 mm right-hand thread, making it compatible with the installation of a sound suppressor.

Reinforced Gearbox V3

At the heart of the replica lies the V3 gearbox, equipped with the following components:

  • 8 mm J-Cage ball bearings are implemented for both the motor and piston gears,
  • while the 8 mm sliding bearing supports the middle gear.
  • A robust steel cylinder enhances durability,
  • accompanied by a set of CNC steel gears featuring a 16:1 ratio.
  • The design includes a reinforced piston with a steel jaw,
  • as well as aluminum heads and nozzle for optimal performance.

Dark Matter High Speed 27-35k brushless motor

Equipped straight from the factory with a premium brushless motor—the Dark Matter High Speed 27-35k—this replica delivers enhanced power, rate of fire, reliability, and efficiency. Designed to handle exceptionally strong springs (up to M190), the motor operates with high torque within a range of 27,000–35,000 RPM.
