RRA SA-P02 PRIME™ HAL™ ETU - Black

Specna Arms Prime

Combination of well-known models from the EDGE™ / EDGE™ 2.0 series along with new internal components. The Prime series offers replicas licensed by companies such as Rock River Arms or Daniel Defense.

All of this, and much more, makes the Specna Arms Prime an interesting option for airsoft players who are looking for a replica that offers very high performance, quality and a premium nano coating on the weapon's body right out of the box, all without having to sacrifice their time and finances for further upgrades.

Unmatched precision

The new PRIME series weapons have incorporated entirely new precision 6.02 mm barrels, which, in combination with the tDC Magnus™ hop-up chamber and Helium™ Flat hop-up rubber, ensure excellent accuracy and stability of the BB.

Internal modification of the gearbox      

Innovation that the PRIME series of weapons can boast is the new Aether^TM gearbox, which comes with several exciting new features.

Air set consists of a polymer piston with steel teeth and a metal piston head. Steel cylinder with grooves that help dissipate heat is excellently sealed with two O-rings at the head of the cylinder. The O-ring can also be found on the metal nozzle.

Everything runs on CNC wheels at a ratio of 16:1, which we can see in all high-end upgrade setups these days. The wheels are seated in 8 mm steel bearings. Two of these are ball bearings, and the manufacturer used sliding bearings for the central gear wheel.

The "brain" of the entire gearbox is the Aster II processor unit from Gate or the new Kestrel unit, which we will describe further below. Just like with the Edge 2.0 series, a special adjustable 90° trigger is used here, now called the Quantum Trigger 2. You will appreciate it, along with the processor unit, primarily for its great responsiveness and short travel when "tapping".

External modification of the gearbox

The PRIME series weapons, like their predecessors from the EDGE 2.0 series, are equipped with the QD ESA 2 system for quick spring replacement.

One of the most important elements of the Aether^TM gearbox is its reinforcement at the front. In these areas near the original Orion^TM gearbox, there were occasional breakages of the gearbox when using stronger springs. That's already a thing of the past thanks to the extra material added in the most stressed areas. This is also aided by the polished radiuses at the front, but now also at the rear of the window for the steel cylinder.

Last but not least, we must not forget to mention the windows in the gearbox for checking the spring during pre-cocking and setting the AOE, or for releasing the spring, for example. Along with the screw holes for perfect axis adjustment, the Aether^TM gearbox is ideal for any potential upgrade.

Brushless motor already from production

If Aster II and Kestrel are to be the brains of the whole setup, then the brushless Dark MatterTM motor must undoubtedly be the heart. It is certainly the most groundbreaking element that we have not seen in out of the box replicas until now.

What is a brushless motor?

Brushless motors are the latest generation of motors that, thanks to modern technologies, no longer contain carbon brushes, which can burn out over time, leading to the malfunction of the replica.

Advantages of brushless motors:

1. The main advantage of brushless motors is their extremely low consumption. With one battery, you can fire up to 5 times more BBs. Finally, small 1000mAh batteries, which are for example stored in the foregrip are getting their chance!
2. The motor, thanks to the absence of brushes, can deliver greater power in an even shorter time. You can especially notice it in the quick response and high fire rate.

HAL Processor unit

• Magnetic trigger based on Hall effect
• Optical cycle detection
• Adjustable trigger sensitivity - 5 levels - 20 - 100%
• Binary trigger - gun fires when trigger is pulled and released
• Active brake - when using weak springs, inconsistency can occur when firing single shots, such as when a replica fires twice on one trigger pull - active brake solves this problem by stopping the motor after each shot
• Piston pre-cocking - 6 levels - Piston pre-cocking improves trigger response by leaving the piston in one of the preset rear positions after each shot. This means that with each shot, the motor does not have to retract and then release the piston, it just releases it.
• Li-Po alarm - if the charge of the used Li-Po or Li-Ion battery drops below 5.0V, the gun will vibrate and emit audible signals
• Programmable firing modes - Automatic, 3-shot, 5-shot, semi-automatic
• ''AUG'' mode - when the trigger is pulled the weapon fires semi-automatic, when the trigger is fully pulled the weapon fires fully-automatic.
