RRA SA-P24 Prime™ Aster II ETU BLDC™ - Black

The Specna Arms RRA SA-P24 PRIME™ Aster II ETU BLDC™ is a premium AEG carbine from the PRIME™ line. It’s based on the well-known EDGE™ series, but fitted with completely new internals for players who want high performance and reliability without having to upgrade immediately.

Externals and build

The receiver is finished with Nano Coating, which helps to protect against scratches and wear, keeping the rifle looking good even after many games.
The outer barrel carries an individual serial number confirmed by a hologram.

Key external features:

• 14mm CCW thread on the muzzle – ready for suppressors or flash hiders

• QD-type pistol grip for a secure and comfortable hold

• 6.02 mm precision steel inner barrel for better accuracy and shot consistency

The package also includes an Angled Forward Grip, improving weapon control during rapid fire and quick transitions.

Accuracy – Magnus™ TDC + Helium™ Flat Hop

The replica is equipped with the Magnus™ TDC (Top Down Center) rotary Hop-Up chamber, which:

• applies pressure from directly above and centered on the BB,

• allows very fine and stable Hop-Up adjustment,

• performs well with heavier BB weights.

It works together with a Helium™ Flat Hop bucking to:

• stabilise the BB in flight,

• keep a flat trajectory with a slight lift at longer ranges.

You get excellent accuracy right out of the box, with no immediate need to swap chamber or bucking.

Æther™ Gearbox – reinforced internals

Inside, the rifle features the reinforced Æther™ gearbox (patent protected), designed to handle strong springs (up to around M140) and to make maintenance easier.

Æther™ Gearbox benefits:

• main spring release function – kinder to the internals after games

• inspection windows for pre-cocking and AOE

• reinforced front section of the shell

• additional inspection windows for easier priming and checking

• trigger adjustment function

• guide screw holes for precise shell alignment

Internal components:

• reinforced polymer piston with full steel rack

• aluminium pneumatic assembly

• bearing spring guide

• CNC steel gears with 16:1 ratio

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

• GATE solarTrigger™ compatible with the Aster II

Dark Matter™ brushless motor – the power core

The SA-P24 PRIME uses the Specna Arms Dark Matter™ High Speed 27–35k brushless motor. Compared to a standard brushed motor, it is designed for:

• smooth operation,

• handling higher rates of fire and stronger springs,

• increased durability thanks to the absence of carbon brushes.

This makes the replica suitable for intensive use and more demanding playstyles.

GATE Aster II Bluetooth® ETU – smart control

From factory, the rifle is fitted with the GATE Aster II Bluetooth® ETU module, replacing traditional mechanical contacts with a programmable electronic unit.

Aster II main features:

• Bluetooth® connectivity to a mobile app – adjust the rifle from your phone

• extensive trigger behaviour customisation

• Binary trigger (shot on pull and release)

• pre-cocking settings for instant shots

• Active Brake

• battery and motor protection, including built-in fuse and low battery warning

• Sniper mode and other advanced firing options

The unit is manufactured to the MIL-V-173C standard, improving resistance to harsh weather conditions.

ESA2™ – quick spring change

The improved ESA2™ quick-change spring system lets you change the main spring without fully disassembling the gearbox. Split the rifle, pull out the spring guide, swap the spring, done.

In the box you get two springs – M90 and M135:

• M90 – ideal for CQB and lower velocity limits,

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

This makes the SA-P24 PRIME a flexible platform for different fields and events.
