SA PRIME™ Kalashnikov Assault Rifle – The Ultimate Airsoft AK
Are you a fan of Eastern Bloc firearms looking for a top-tier AK with outstanding durability and loaded with the best possible components? A ready-to-go rifle that, right out of the box, delivers a fierce performance and will frustrate your opponents on the field? Then you’re in the right place. Congratulations, you’ve found the holy grail of modern airsoft AK rifles.
AK, officially known as the Kalashnikov Assault Rifle, was developed in the Soviet Union by Mikhail Kalashnikov in the late 1940s. It became the standard assault rifle of the Soviet armed forces (AK-47) and, thanks to its durability, reliability, and ease of use, it is still in use worldwide. The AK-47 uses a 7.62×39mm cartridge, offering good stopping power and range. In the 1970s, the modernized AK-74 with a smaller 5.45×39mm cartridge was introduced.
Prime™ is the flagship line. It represents the best, most refined, upgraded, perfected, and reliable rifles that Specna Arms has to offer. In short, Specna decided to take the perfect steel J-Series Edge body with a Nano Coating finish for increased scratch resistance and durability, and pack it full of upgraded internals. The rifle’s body is matte-coated, giving it an elegant appearance. The proven AK rifle design provides comfortable handling and easy operation. If you want a universal airsoft AK built from the best components that requires no further upgrades, the PRIME™ J-Series is the right choice. From a fast CQB blaster to a precise DMR rifle for semi-auto fire – that’s the magic of PRIME™. The package includes 2 S-Mag mid-cap magazines (175 BBs) and a speedloader for quick reloading.
The SA AK-74S variant comes with a metal folding skeleton stock and polymer handguard in Plum finish. The rifle does not feature RIS rails or M-LOK/KeyMod slots. However, it includes a side mount rail compatible with AK-style side mounts, allowing you to install optics.
Internal Parts and GATE ASTER SE V3 ETU
Inside you’ll find a precision brushless Dark Matter motor with 27,000 rpm. This motor ensures higher efficiency, better performance, and further increases rate of fire and trigger response. It provides up to 5x more shots on the same battery compared to traditional motors (5000+ shots with an 11.1V 1000mAh pack). It’s housed in a durable aluminum casing, capable of handling springs up to M190.
The reinforced V3 gearbox handles AEG springs up to M140. Inside, you’ll find CNC steel 16:1 gears – the ideal ratio for high RoF and durability, especially with a Specna Arms M135 spring. 8mm J-Cage bearings are used: ball bearings on the motor and piston gear, with a bushing on the sector gear for added strength. This configuration, based on extensive testing, offers the perfect balance of durability and speed.
Reinforced polycarbonate piston with 14 steel teeth ensures optimal AoE and prevents gun lock-up. It’s strong yet lightweight to maintain performance. The piston is paired with a CNC piston head with enlarged ports for efficient air routing into a CNC cylinder head with double O-rings, seated in a stainless steel ribbed cylinder for cooling during full-auto bursts. Air is directed via a CNC nozzle mounted on a reinforced tappet plate. Feeding is guaranteed by a strong tappet spring and a sector gear delayer.
The AK PRIME™ rifle is equipped with the GATE ASTER SE V3 electronic control unit, which ensures safe trigger switching, protects internals, improves trigger response, extends battery life, and boosts RoF. It supports safe use of 7.4V and 11.1V Li-Pol batteries. The battery connector is T-Dean, located under the dust cover. ASTER II V3 features include active braking, binary trigger, adjustable trigger sensitivity, precocking, and programmable firing modes, including DMR mode.
Accuracy is delivered by a 6.02mm precision inner barrel, paired with a Helium Flat-Hop bucking in the redesigned MAGNUS™ TDC hop-up chamber. The package also includes 3 AEG springs of different strengths (M90, M115, M135). Thanks to the ESA2 quick spring change system, swapping springs is quick and easy – just remove the buffer tube and remove the spring guide cover.
We recommend purchasing the GATE Blu-Link Bluetooth module (product code: BLU-L) to control ASTER via the GCS app for Android, iOS, or Windows/Mac. The app provides full functionality and easy firmware updates directly on your phone. Without this module, programming is done via the trigger, with limited features.

Warnings
- Some manufacturers’ springs are overrated (e.g., M130 may equal M140–150), potentially exceeding gearbox durability. Use only Specna Arms springs included. With other brands, M120 strength is recommended to prevent damage.
- When using springs with progressive (irregular) winding, ensure the tighter coil end is seated on the spring guide facing outward from the gearbox.
- Never store the rifle with the battery connected.
- Never store the rifle with pre-cocking enabled. Always release the piston before storage to avoid spring damage.
