Full description


The Edge series are the top tier of AEGs from Specna Arms. They make use of the Orion upgraded gearbox with an ESA quick change spring system and come fitted with a Gate TITAN Advanced unit straight from the factory, giving the gun top of the line performance, along with remarkable external fit and finish thanks to the licensed River Rock Arms Receiver.

The Gate TITAN unit fitted to the Edge series is the premier trigger unit available today. It has no mechanical sensors, and relies on optical gates to identify a number of parameters, such as trigger position, sector gear position. Using this information the TITAN unit can work out exactly how far through the gearbox cycle it is and determine exactly what the gearbox is doing. This gives TITAN users access to features such as pre-cocking, allowing the TITAN to provide lightening fast trigger response, even on low power or mostly drained batteries. The kit also detects whether the gearbox has completed a complete cycle and get work out if there are any faults for every shot fired. This is a fantastic bit of in-built gearbox protection, where the TITAN will shut down if an error is detected, protecting both the TITAN unit and the mechanical components inside the gearbox too. Thanks to 5 trigger sensors, you can choose an exact point where your trigger activates, giving fine control over your shot release. This also allows you to set up a 2 stage trigger, similar to an AUG, but in an AR platform. The TITAN also has features, such as an adjustable sniper delay, preventing a follow up shot within a set time period between .5 and 3 seconds. Thanks to all of this technology the TITAN removes finicky trigger contacts and allows all of this adjustability from you PC, tablet, laptop or Android device, meaning even on-site fiddling is possible.

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 bird cage style 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 traditional A1 style handguard is built from a durable polymer, which makes it durable and lightweight, meaning that fatigue won't ruin your day!

The assembly is secured to the receiver tightly via a traditional Delta Ring and has absolutely no wobble, helping this rifle feel more like the real thing in the shoulder. The receiver itself features a sturdy carry handle with integrated rear sight, which can be removed to reveal a standard 20mm RIS rail for attaching your preferred aiming device

The six position sliding stock at the rear is where the battery is housed, and connects to a Deans connector (adaptor included), and you will also notice an ambidextrous sling plate for left and right handed sling users.

The quality continues internally with a wealth of parts which would be considered an 'upgrade' on any other AEG. A rotary HOP unit gives you fine and precise control over flight path, and being coupled with a precision 6.03mm barrel makes for a very pleasant firing experience. The 'ORION Gearbox' featured inside has a reinforced frame to handle high power springs and is designed around their quick change spring system. Other perks of the ORION Gearbox are: Reinforced Polymer Piston with Steel rack, Aluminium sealed Nozzle, Aluminium double sealed Cylinder Head, Aluminium double sealed Piston Head w/ bearings, Steel Gears and 8mm Bearings. All of this comes together to seal the perfect package for those who want the best of external and internal quality.

Included in the box are two mid-cap 125rnd 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.

This replica is a beautiful amalgamation of the lush exterior build quality that Specna Arms bring to the table, and the mind-blowing control that the Gate TITAN MOSFET gives you over your replica. This all comes together to create a RIF which is as reliable as it is good looking, which can be tweaked to your heart's content to make it the rifle that stays in your collection for a lifetime.
