Specna Arms SA-PJ17 PRIME BLDC – AK AEG Airsoft Rifle, GATE ASTER, Black/Wood

Specna Arms SA-PJ17 PRIME BLDC – Classic AK Design with Advanced Brushless Technology

Traditional AK styling, extensive steel construction, genuine wooden furniture and modern internal technology. The Specna Arms SA-PJ17 PRIME BLDC combines the authentic appearance of a classic AK with the advanced performance of the PRIME™ J-Series.

Developed from the proven J-Series EDGE 2.0™, the PRIME™ J-Series introduces upgraded internal components designed for demanding airsoft players.

The SA-PJ17 combines a brushless BLDC™ motor system, GATE ASTER electronic control unit, Magnus™ TDC Hop-Up chamber and CNC-machined 16:1 steel gears.

Its classic external configuration features real wooden handguards and a folding steel stock, while the upgraded internal components provide a modern foundation for responsive electric operation.

BLDC™ Brushless Motor Technology

The BLDC™ (Brushless Direct Current) motor system eliminates traditional carbon brushes and uses electronic commutation.

This technology offers several advantages over conventional brushed motors:

• Rapid trigger response for responsive shooting.

• High starting torque for efficient gearbox operation.

• Improved energy efficiency and battery utilisation.

• Reduced mechanical wear thanks to the absence of carbon brushes.

• Lower heat generation during operation.

• Smooth and quiet motor operation.

• Stable performance at higher rotational speeds.

• Greater performance potential for demanding spring configurations.

The Specna Arms Dark Matter™ High Speed 27–35k motor system is designed to provide dynamic performance and responsive operation.

GATE ASTER Electronic Control Unit

The SA-PJ17 PRIME features an integrated GATE ASTER electronic control system.

Unlike conventional mechanical trigger contacts, electronic control allows more precise management of the firing cycle.

The combination of GATE ASTER and brushless motor technology provides a responsive foundation for semi-automatic operation and demanding airsoft gameplay.

Magnus™ TDC Hop-Up Chamber

The rifle is equipped with the Specna Arms Magnus™ TDC Hop-Up chamber.

TDC stands for Top Dead Center, referring to a design in which Hop-Up pressure is applied from above along the barrel's centreline.

This arrangement supports precise adjustment and consistent BB backspin.

Key benefits include:

• Precise Hop-Up pressure adjustment.

• Consistent contact with the BB.

• Stable BB trajectory.

• Repeatable adjustment.

• Improved control over the Hop-Up setting.

The chamber is paired with a Specna Arms Helium™ flat Hop-Up bucking, designed to provide consistent contact and stable BB rotation.

6.02 mm Precision Inner Barrel

The rifle features a 6.02 mm precision inner barrel, providing a consistent internal bore for BB travel.

Combined with the Magnus™ chamber and Helium™ bucking, it forms a high-quality foundation for accurate airsoft shooting.

High-quality, dimensionally consistent BBs are recommended for optimal results.

Reinforced Internal Components

The PRIME™ J-Series features upgraded internal components designed for durability and efficient power transmission.

The SA-PJ17 includes:

• CNC-machined steel gears with a 16:1 ratio.

• 8 mm J-Cage ball bearings on selected gear positions.

• 8 mm sliding bearing on the central gear.

• Steel cylinder.

• Reinforced piston with a steel tooth rack.

• Aluminium head.

• Aluminium nozzle.

• 6.02 mm precision inner barrel.

• Magnus™ TDC Hop-Up chamber.

• Helium™ flat Hop-Up bucking.

• GATE ASTER electronic control unit.

The 16:1 gear ratio provides a practical balance between cycle speed and torque transmission.

The reinforced piston with steel teeth is designed to withstand repeated mechanical loading.

ESA2™ Quick Spring Change System

The rifle features the ESA2™ (Easy Spring Access) quick spring change system.

After folding the stock and removing the receiver cover, the spring guide can be accessed without completely disassembling the gearbox.

This makes it easier to adapt the rifle's output to different airsoft field requirements.

Two additional springs, M90 and M135, are supplied with the rifle.

Steel Construction and Genuine Wooden Furniture

The SA-PJ17 PRIME combines steel, aluminium, real wood and polymer.

Steel components include:

• Receiver.

• Receiver cover.

• Outer barrel.

• Muzzle device.

• Trigger guard.

• Magazine catch.

• Fire selector lever.

• Folding stock.

• Gas tube.

• Sling attachment point.

Aluminium is used for selected components, including the sights, side dovetail mounting base and bolt assembly with charging handle.

Genuine wood is used for the handguard and upper gas tube cover, providing the classic appearance and feel associated with traditional AK designs.

Polymer components include the pistol grip and magazine.

Protective Nano Coating

The receiver features a protective nano coating designed to improve scratch resistance.

This finish helps protect the replica's appearance during normal handling and airsoft use.

Each rifle also features an individual serial number.

Folding Steel Stock

The SA-PJ17 is equipped with a folding steel stock.

Folding the stock reduces the overall length of the replica, making transportation and handling in confined spaces more convenient.

A sling attachment point is integrated into the stock assembly.

Side Dovetail Optics Mount

The receiver features a traditional AK-style side dovetail mounting base.

This allows compatible side-mounted optic adapters and accessories to be installed.

Battery Compartment

The battery compartment is located beneath the receiver cover.

It provides space for a compatible stick-type battery, a common configuration for AK-platform AEG rifles.

Battery dimensions and electrical compatibility should be checked before use.

24 mm CW Muzzle Thread

The muzzle device is mounted using a 24 mm clockwise (CW) thread.

Compatible muzzle accessories can be installed using the appropriate mounting system.

Always verify thread compatibility before selecting a suppressor or adapter.
