Specna Arms x KPYK SA-PJ13 Prime Aster ETU BLDC AEG Assault Carbine - Olive

AEG electric carbine replica from the Prime series, inspired by well-known Kalashnikov platforms. Features premium components including a KPYK CRC 1U020 handguard with gas tube cover, a Specna Arms Dark Matter High Speed 27-35K brushless motor, and a Gate Aster V3 control module that enables users to fine-tune replica settings according to individual preferences.

Steel body, Nano Coating finish

Constructed predominantly from steel, with additional components made from aluminum and plastic, the replica features various steel elements, including the body, receiver cover, outer barrel, trigger guard, magazine catch, selector lever, tactical sling loop on the stock, folding stock, gas tube, and cleaning rod. Aluminum is utilized in the handguard, sighting systems, “dovetail” optic mount, and the bolt with cocking handle, as well as the muzzle device. The magazines and pistol grip are crafted from high-strength plastic. Enhanced durability is achieved through a Nano Coating applied to the body, which offers protection against scratches.

The carbine features an aluminum handguard with a gas tube cover from the Ukrainian manufacturer KPYK, model CRC 1U020 built to the M-LOK standard, enabling the mounting of various tactical accessories. An additional Picatinny rail is integrated along the top of the handguard. The weapon also incorporates the classic AK optic mount, known as the “Dovetail”.
