Full description


The Edge series are a new line of replicas from Specna Arms which combine their usual hardy build-quality on the externals with uprated internals, and a Gate TITAN as standard to squeeze every drop of performance out of these rifles. The metal parts of the rifle are finished to an amazing standard, and have lovely USMC markings/trademarks, as well as a unique serial number. The GATE TITAN is the mac-daddy of MOSFETs and allows total control over most aspects of your AEG's operation.

The GATE TITAN is the cutting edge of MOSFET technology and offers a ridiculous amount of setup options to get your replica shooting exactly how you want it to. The TITAN replaces your traditional trigger setup with an optical array, meaning a feather-light trigger pull which can be set to any position you like; you can even setup your trigger to work like the AUG, where a half pull is semi and a full pull is auto. The Advanced Kit's main feature is it's ability to handle pre-cocking, which holds your piston in the 'ready' position, making shots much faster and reducing Piston travel. This gives you a much shorter gap between pulling the trigger and your BB finding its' target, which can be make or break in an Airsoft skirmish. The kit also detects whether a complete cycle has been made, which helps protect your internals, knowing when there's an issue and also ensuring a smooth operation. It also allows complete control over your Rate of Fire, trigger re-set point (at what point in travel your trigger will reset and allow you to fire again) as well as fire mode adjustments. Ever dreamed of running your favourite AEGs on bolt action rules? Now you can! The GATE TITAN has a "Bolt Action Delay" which is essentially an adjustable delay in how fast your trigger can be pulled. By setting this delay to one second or more, it could allow you to run your AEG at 450+ FPS as a bolt action rifle, because you can't physically fire it faster than you have set it. The TITAN kit is incredibly beneficial for AEGs long term as it has lots of smart technology to ensure the rifle runs as it should, and to know when something isn't right. It has incredibly low power consumption which should extend how long your AEG is lasting in the field, removes the need for weak and flimsy trigger contacts and can be updated via the included cable whenever there are major updates for the software. All this can be controlled from your smart phone or laptop, making this the ultimate tool for tinkerers of terror!

The externals are made from a mix of Aluminium and Zinc Alloy which undergo a rigorous course of Sand Blasting, Powder Coating and then Anodising to achieve a world-class finish on their metal-work. This finish is then protected by a 'Nano Coating' finish that reduces scratches. The external trim parts of the rifle such as structural screws and supports are made from Steel to ensure a long-life performance.

The Polymers used throughout are an exceptional quality and feel really good in the hands, the Pistol Grip being textured to promote grip in all conditions. The pistol grip has a neat design which allows you quick access to the motor without the need for tools.

At the muzzle end of the replica is a birdcage flash hider which can be screwed off to reveal a 14mm CCW thread underneath. This lets you attach Suppressors, Tracer Units, Muzzle Brakes or any compatible muzzle device to further enhance the looks or performance of your AEG. The handguard is built from Aluminium and Zinc Alloys which makes it very tough and durable, and features a full-length top 20mm rail, but is an M-LOK design which comes with short and medium length 20mm adaptors pre-installed.

The entire assembly is secured to the receiver tightly and has absolutely no wobble, helping this rifle feel more like the real thing in the shoulder. The rear of the replica features a CTR style sliding stock, and has a Deans connector inside the buffer tube to connect your battery. You will also notice an ambidextrous sling plate for left and right handed sling users.

Internally this replica features Specna's Enter & Convert™ quick change spring system that means once the gearbox is removed from the shell, the main spring is easily accessible for rapid changes in output power. Other internal parts include a Steel Spring Guide, reinforced Steel Gears, a lightweight Polymer Piston, Aluminium Piston Head as well as an Alloy Cylinder Head and Nozzle. The mock bolt stop is functional and allows you to make easy HOP adjustments without having to hold the charging handle to the rear.

Included in the box is a high capacity 300rnd magazines of a modern P-Mag design, which has tiny Specna Arms logos used as a stippling pattern which looks absolutely fantastic! Also included is an ID lanyard, an instruction manual and a certificate of testing from the manufacturer, along with Gate TITAN accessories such as a cable and diagnostic adaptor.

This Airsoft Electric Gun is a sure choice for those looking for a major step-up in performance, those who like to tinker with their AEGs and for those who want to be at the absolute top of their game. If you're looking for the perfect blend between hardy metal externals and TM-killing performance internally, this is the replica for you.

Special Instructions:

The externals of the replica are metal where they would be on the real world gun. This includes things like the outer barrel, handguard, and receiver. If a real world gun has polymer parts then the gun will still be marked as full metal externals, examples of this would be an M4, where the Stock and Pistol grip are always made from Polymer.
