Specna Arms SA-X02 EDGE 2.0™ AR-9 SMG w/Gate ASTER MOSFET

The AR-9 platform is becoming very popular these days, and there is little worse than spending time perfecting your setup only for it to look like everyone else's! Enter the SA-X02, Specna Arms' take on the 9mm AR platform. The X series makes use of a uniquely designed alloy AR-9 receiver with Specna's hard-wearing Nanocoating finish and stylish weight-reducing cuts throughout to separate it from other AR-9 platforms, and is pre-upgraded on the inside with some superb high end parts to give it the performance to duke it out with the ARP9, X-9 and other 9mm AR platforms. To the ARP9, the X02 says "bring it on!"

Starting at the tip of the 8.5-inch alloy outer barrel we have a stylish compensator-style muzzle device with multiple ports on all sides which serve to reduce recoil and muzzle flash on a real rifle. This muzzle device really suits the style of the SA-X02, but if you want to change it out for a tracer unit (we bet you do!) you can thanks to the barrel's 14mm CCW male threading.

The handguard of the SA-X02 is officially licensed by Strike Industries and is equipped with M-LOK negative space attachment slots at the 3, 6 and 9 o'clock positions, making it ready for accessories without the excess weight of a quad Picatinny rail system. Strike Industries trademarks can be found laser engraved at the base of the handguard near the barrel nut, with an M-LOK logo just in front. The handguard also has the classic Strike Industries style handguard ports with their unique shape which only adds to the cutting-edge looks of the SA-X02.

The 12 o'clock position sports a 20mm Picatinny rail section at the front, ideally positioned for the pre-mounted flip-up front sight or a tactical flashlight, and another section at the rear which mates seamlessly with the receiver rail to provide a long upper rail allowing optical sights of practically any length to be mounted. Between the two rail sections, there is a relief cut which is a perfect index point for using the "thumb over bore" grip, allowing for greater control over the muzzle when transitioning between targets.

As it comes in the box the SA-X02 comes with the Specna Arms Angular Front Grip from their SAAS (Specna Arms Accessory System) range pre-installed at the 6 o'clock position. The grip is constructed from aluminium and provides a comfortable wrist position when shooting which is the perfect compromise between a vertical grip and a horizontal handguard. It is nice that Specna included this with the SMG, but if you have a preferred style of grip you can simply remove it and add any M-LOK compatible grip, or an M-LOK to 20mm Picatinny adapter to make use of grips for 20mm rails.

As we arrive at the receiver we can see an M4/AR15 style layout, but a completely original receiver design with loads of ergonomic enhancements machined in. At the front of the magazine well we can take note of the gripping texture which allows greater control of the SMG when using the "magwell grip" which is a great technique for exchanging fire at close range. The magazine well has a built-in flare to help guide your magazine in during an adrenaline-fueled reload in the thick of it, and each side of the magazine well has weight reducing relief cuts, with the deeply and crisply engraved trademarks on the left side.

The trademarks on the receiver are Specna's own, with the SA in a box logo at the top, and "X-SERIES" followed by "9x19 mm" and the serial number just below. The markings are immaculately engraved as Specna Arms are known for, and do not detract from the realism aspect, as there is no "6mm" or "for Airsoft only" to be seen. Nice work Specna!

The magazine release is located on the bottom of the SMG, positioned in the centre to allow for easy access for both left and right-handed shooters. This mag release is seriously massive, giving you absolutely no chance of missing it when a quick reload is needed. The texture on its surface also guarantees grip in any weather conditions. The trigger guard follows just behind the mag release and is built into the receiver similarly to modern "billet" AR15 receivers, increasing strength by removing the M4/AR15 modular trigger guard system which is a known point of weakness in the design. The trigger guard itself is enlarged to allow easy access to the trigger, even when wearing thick gloves, and its angle matches that of the magazine well perfectly, showing Specna's consideration to aesthetics when designing the X-series.

Within the trigger guard, we can find the flat trigger, but this isn't just any flat trigger! This is the Gate Solar trigger, based on their successful Quantum trigger. Designed to interact with the optical sensors inside the Gate ASTER MOSFET/ETU, the Solar allows the trigger travel and the sensitivity to be adjusted to suit your preferences using Gate's Control Station app, the Gate Blu-Link or USB-Link (available separately). The flat trigger design is perfect for rapid semi-auto shots in CQB and has a textured front surface for optimal grip, and a short finger ledge to keep your trigger finger where it needs to be.

The HOP-up unit of the SA-X02 is located right where we would expect it; inside the mock ejection port, concealed behind the steel mock bolt. Pulling the charging handle, located at the top rear of the receiver, will retract the mock bolt and lock it open, revealing the rotary HOP-up dial beneath. The rotary unit design is the latest for the M4/AR15 and is known to hold its adjustments well under the vibration of full auto fire, and provides finer increments of adjustment than the legacy gear HOP-up unit.

The HOP-up rubber installed within this unit is the Specna Arms Helium™, providing plenty of lift and allowing heavier BBs to be used to extend the SA-X02's range. With your HOP-up adjustment complete you can hit the bolt catch on the centre left of the receiver to send the mock bolt home with a satisfying "clank".

The SA-X02's pistol grip is a modern ergonomic design with a filled backstrap and textured panels on either side for optimal gripping qualities. The grip is set at a more vertical angle than usual, making it great for use with modern shooting stances and pairing perfectly with the super compact PDW stock, adding to the beastly CQB qualities of the platform.

The stock is the standard Specna Arms PDW stock, complete with Specna's bespoke texturing to make it easy to extend. The QD sockets usually found on either side in other brands' PDW stocks are not present on the Specna stock, instead, we have a single centrally positioned socket, meaning if you switch shoulders to take a tight corner you don't have to mess with the sling. The adjustment button is on the base of the stock and has a textured surface to ensure it is easy to adjust mid-game.

The battery compartment is inside the buffer tube of the stock, meaning battery space is a bit tight inside the SA-X02. Accessing the battery compartment only requires that you unthread the buffer tube with the stock at its longest position, and inside you will find a Deans battery connector, providing lower resistance and higher electrical efficiency than the more common mini-Tamiya connector. For the SA-X02 we recommend the Specna Arms 7.4V 600mAh LiPo PDW Stick battery, but if you add the Specna Arms PDW battery extension you can use a 7.4V 1300mAh LiPo stick battery. If your battery stash is full of mini-Tamiya batteries, no need to buy again, the SA-X02 comes with a Deans to mini-Tamiya adapter!

Inside the SA-X02 we are treated to the usual Specna Arms goodies, starting with the ORION™ gearbox. The ORION™ boasts a reinforced polymer piston with steel teeth, an aluminium nozzle and cylinder head, a quick change spring guide equipped with ball bearings to reduce rotational stress, and a solid set of steel gears running on 8mm ball bearing bushings. Sounds good, but it gets even better!

The SA-X02 is pre-wired with the Gate ASTER MOSFET/ETU which provides superior electrical efficiency, protects your battery from reverse polarity and has a whole host of advanced smart functions which can be unlocked by using the Gate Control Station app, the Gate Blu-link, the Gate USB-link or the Gate Programming card (available separately). To give the gearbox the pull it needs to do the ASTER justice, Specna have installed a high torque motor with Neodymium magnets which helps with the split-second trigger response but is also capable of pulling far stronger springs than the M90 which comes pre-installed.

So, if you want to jump on the AR-9 bandwagon but you are a unique character who wants to stand out, but not at the cost of performance, the SA-X02 would be perfect for you. The SA-X02 wants for nothing on the outside with its full metal construction and high quality Nanocoating finish, and on the inside it is ready to contend with even upgraded setups!
