Full description


This Airsoft Electric Gun from Specna Arms is another in the EDGE series and is where high quality external materials, top spec internal components and a reasonable price point all meet in the middle to create a sure-choice AEG. The external build quality is absolutely excellent on Specna models, and uses a combination of Zinc Aluminium, Alloys and Steel for a rock-solid feeling rifle in the shoulder, and a long lasting finish which is protected by a Nano Coating to reduce scratching. The replica is fully licensed and features markings from Rock River Arms, a firearms manufacturer from Illinois, USA. Furthermore, it is authenticated with a hologram seal so that you know you have the genuine article. The markings on the receiver are engraved and include a unique serial number.

Externally the replica features a 14mm CCW thread which comes with a stubby style suppressor already installed. With this unscrewed and removed, you have access to the thread to install whatever muzzle device you desire. The handguard is a four-point 20mm RIS and is ready for any RIS compatible accessories out of the box, but comes included with a Polymer short foregrip for better control over the replica. The receiver also has a 20mm rail on top which is ideal for scopes and sights, but has a flip-up rear ironsight installed out of the box. The Pistol Grip and Stock are made from high density Polymers which makes them feel great, and the pistol grip is a quick access design which gives you easy access to the motor. The buffer tube has an Ambidextrous Sling Plate installed which is ready for slings from either side of the replica, making this a great choice for left handed players who cannot adapt. The six position sliding Crane Stock at the rear is where the battery is housed and has sockets for a QD sling point if you wish to run this kind of setup. The battery connection is Deans out of the box, however there is an adapter included to convert the connection to a small Tamiya, to be compatible with most batteries.

Internally, this Gun has a huge range of features that make it a prime choice over other models in its' price range. The first of many uprated components is a 6.03mm Precision Inner Barrel, and a Rotary HOP Unit for fine control over your BB's backspin, allowing for an increase in range and consistency (when using the right BBs and settings). The HOP Unit has a Helium™ Flat HOP Bucking which interacts very evenly with the BB, and makes for excellent and stable lift. As with any premium Specna Model, you have the ORION Gearbox inside, with the updated ESA2™ Quick Change Spring System that allows for rapid Main Spring changes from the Buffer Tube, without having to remove or disassemble the Gearbox. The ORION Gearbox also features, a lightweight Polymer Piston with a Full Steel Rack, double-sealed Piston Head with Bearings, Air-Sealed Nozzle, Double Sealed Cylinder Head, Spring Guide on Bearings, a set of Steel Gears and 8mm Bearings. This is an impressive list, but it doesn't end there...

The main party trick of the Specna Arms SA-E05 Edge 2.0 is the GATE ASTER™ MOSFET, which is a massive step above the GATE X-ASR Module that was included with the previous models. The ASTER™ provides amazing features such as 'Polarity Inversion Protection', which prevents damage from mis-use of Batteries. An Optical Sensor makes for an incredible Trigger Pull (the smallest twitch will fire the Gun, which is great for long-term endurance). The Trigger can also be set to one of 250 sensitivity settings!  This Trigger is paired with the Solar™ Electronic Trigger which has a very pleasant travel and pull, and will take your skirmish-performance to another level. The ASTER™ interacts with the GATE Control Station Application, allowing you to modify your Gun from the comfort of a device or computer, and a handy RGD LED Diode system makes for simply programming. If you want to perform advanced programming, you'll need the GATE USB-Link for full control over the ASTER™ MOSFET.

If you're looking for a replica that has all the internal components of a top-tier Airsoft gun, the external build quality of a custom build, genuine licensed Trademarks and the price point of a standard AEG, you've come to the right place. The Specna Arms SA-E04 perfectly balances, fun, quality and price point.
