SA-P20 Prime™ Aster II ETU BLDC™ - Chaos Bronze

The Specna Arms SA-P20 Prime™ Aster II ETU BLDC™ airsoft carbine is a modern replica from the PRIME™ series, combining robust externals with high-end internals. It’s made for players who want strong performance and reliability without immediate upgrades.

Externals

The rifle is built to be durable and visually attractive:

• Nano Coating finish on the body – helps to protect against scratches and wear

• Individual serial number on the barrel with hologram confirmation

• 14mm CCW threaded outer barrel – ready for suppressors / flash hiders

• Folding sights – usable alone or together with optics

• 6.02 mm precision steel inner barrel – for high accuracy and consistency

The package also includes an Angled Forward Grip, giving better control over the rifle during rapid fire and quick transitions.

Accuracy – Magnus™ TDC + Helium™ Flat Hop

For accuracy, the SA-P20 uses the Magnus™ TDC (Top Down Center) rotary Hop-Up chamber:

• centered, top-down pressure on the BB,

• fine and stable Hop-Up adjustment,

• very good performance with heavier BBs.

This is paired with a Helium™ Flat Hop rubber, which:

• improves BB stability in flight,

• helps achieve a flatter trajectory and reliable long-range hits.

Together, these components provide excellent accuracy out of the box.

Æther™ Gearbox – reinforced internals

Inside the rifle sits the reinforced Æther™ Gearbox (patent protected), designed to handle strong springs and intensive use.

Æther™ Gearbox features:

• Anti-Reversal release window – easier servicing

• inspection windows for pre-cocking and AOE

• reinforced high-stress areas of the shell

• motor pinion inspection window

• trigger adjustment function

• screw holes for precise frame alignment

Internal parts include:

• reinforced polymer piston with full steel rack

• aluminium head and nozzle, steel cylinder

• bearing steel spring guide

• CNC steel gears with 16:1 ratio

• 8mm J-Cage ball bearings and 8mm plain bearings

• GATE SolarTrigger™ compatible with the Aster II unit

Dark Matter™ brushless motor – modern drive system

The SA-P20 PRIME is driven by a Specna Arms Dark Matter™ High Speed 27–35k brushless motor. Compared to brushed motors, it provides:

• smooth, efficient operation

• ability to handle higher stress and stronger springs

• longer lifespan due to the lack of carbon brushes

This translates into fast trigger response and stable performance even under heavy use.

GATE Aster II Bluetooth® ETU – smart electronics

The rifle comes factory-fitted with the GATE™ Aster II Bluetooth® ETU module, replacing mechanical trigger contacts with a programmable electronic unit.

Main Aster II features:

• Bluetooth® connectivity to a mobile app – configure the rifle via your phone

• Binary trigger – shot on pull and release

• pre-cocking – for instant shot response

• Active Brake

• battery and motor protection, integrated fuse

• low battery warning

• Sniper mode and other advanced settings

• works with both brushed and brushless motors

The unit is manufactured according to MIL-V-173C military standard, improving resistance to adverse conditions.

ESA2™ – quick spring change

The Enhanced ESA2™ quick-change spring system allows you to adjust the replica’s power quickly and efficiently without tools:

• simply open the rifle, remove the spring guide and swap the spring.

Included springs:

• M90 – ideal for indoor / CQB games

• M135 – for outdoor games with higher limits (always follow local field rules)

This gives the SA-P20 PRIME great flexibility across different fields and event types.
