Meet the PRIME™ by Specna Arms®, the epitome of airsoft excellence. PRIME™ redefines standards, offering top-tier performance straight out of the box for an unmatched experience. The revolutionary AETHER™ gearbox ensures unparalleled reliability and performance. Each PRIME™ replica features an Electronic Trigger Unit (ETU) with easy programmable modes and perfect trigger response. The MAGNUS™ hop-up chamber delivers unprecedented precision, paired with HELIUM™ flat bucking and a 6.02mm stainless steel inner barrel for enhanced accuracy. The upgraded ESA2 system requires no tools and allows you to change the main spring in less than a minute. Experience airsoft with PRIME™ by Specna Arms® - where innovation meets excellence.
Based on the experience of airsoft players and technicians in our R&D department, we have identified the four most commonly upgraded replica components. By analyzing these components, we have sought to bring our factory replicas closer to custom builds. Leveraging the extensive airsoft experience of our R&D and Product teams, and our long-standing market presence, we have implemented technological processes and servicing techniques that mirror those used in the production of tuning parts and custom builds. The result is a product that we believe will satisfy even the most demanding airsoft players.

gearbox
The second most commonly modified component of an airsoft replica is the gearbox. In this case, we decided not to compromise and completely redesigned the heart of the PRIME™ line. We started from scratch, designing an entirely new gearbox shell that offers not only exceptional durability but also numerous features for those who want to know how their replica works.
The AETHER™ gearbox shell has been engineered to provide the highest durability available in a factory replica. At the same time, it adheres to one of our core brand principles: high compatibility with parts from other manufacturers. This makes it an excellent foundation for the most demanding custom builds and can be used in other replicas as well.
We have reinforced critical areas such as the front of the gearbox shell and the spring guide base, while paying close attention to the cylinder window geometry to minimize stress on the pneumatic system's axis.
To ensure seamless interaction between the piston and piston gear, we have included inspection holes for checking the Angle of Engagement (AOE) and pre-cocking. This allows you to verify that the piston gear correctly engages the first tooth of the piston or that the cycle stops at the appropriate position, it also lets you check for Premature Engagement (PME).
With future HPA upgrades in mind, we've designed the gearbox shell to allow for horizontal adjustment, ensuring optimal performance and a great air seal.
To ensure smooth operation, we've employed 8mm J-cage ball bearings on both the sector and bevel gears. Simulation and load testing have revealed additional stress on the spur gear seat in traditional gearbox setups. Therefore, we've implemented a steel bushing at this location to provide maximum durability.
To facilitate gearbox maintenance, servicing, and in case of gearset jams, we've included an inspection hole for releasing the anti-reversal latch and checking the bevel gear condition.
Simplicity at its best! A small screw located behind the trigger axis allows for pre-tension adjustment on any V2 gearbox trigger.
For those seeking modern solutions, we have prepared a gearbox shell designed to work with magazine sensors for GATE® ASTER II™ and TITAN II™ systems. The GATE® ASTER II™ system is available in select models. The magazine sensor is sold separately.
Brushless motor
The final component identified by our R&D department was the motor. Traditionally, users had to choose between high torque or high speed motors. However, with the implementation of BLDC technology, this choice is no longer necessary. Brushless motors allow us to achieve both high torque and high speed simultaneously.
We were the first manufacturer in the world to present a line of replicas with BLDC motors installed straight from the box.
A great motor is just the beginning. To ensure optimal motor-to-spur gear alignment, we've introduced a new pistol grip with an improved QD system and refined motor angle.
Improved 
Years ago, we were the first to introduce the tool-less spring change system, SAEC™, which evolved into the ESA2™ standard. Now, we present an improved ESA2™ standard. To increase durability and reliability, we have increased the wall thickness of the stock tube guide rod by over 50%. Simultaneously, to distribute stress more evenly and increase the stability of the main spring guide, we have extended the effective thread of the guide rod.
