Unfortunately, it’s time for me to part ways with my prized pew pew. Due to buying my first property, I’m having to raise some extra cash to brighten the place up. This is certainly a reluctant sale.


In terms of performance, this gun is an absolute beast. The hop dial is numbered 0-15, I use it mainly as a DMR with .32g BBs, which can be over-hopped when the hop is set to 4 or 5, so you can imagine how much hop you can get out of this thing. It can hop any weight BB that I’ve ever come across (I’ve even tried the longbow .50g BBs).

In terms of range, it shoots as far, if not further than any other AEG I’ve ever shot or seen shot and competes with fully upgraded VSRs at my local site.

The fire rate is incredible for an AEG. I have shot this at multiple sites in the UK, and upon unleashing a full auto burst, it’s not uncommon for someone to turn and shout “what the [email protected] is that!?” (video can be provided on request)

Original features:

·        Aluminum alloy receiver

·        Alpha 9" metal handguard

·        8mm ball bearing bushings

·        Quick change spring system

·        Locking bolt and bolt release

·        Ambidextrous sling loops

·        Adjustable iron sights

·        Ambidextrous fire selector

·        Integrated MOSFET

·        Adjustable rotary hop-up

·        Easy maintenance spring guide

·        Anti-corrosion gearbox coating

·        Krytac 20K motor

·        Tempurature and wear resistant bucking

·        6 position Krytac battery stock


Krytacs are known for being fantastic out of the box, unfortunately the stock gears began overspinning and eventually managed to strip themselves a few months after purchasing.

I has ASPUK fix the gears and they installed ASG ultimate 16:1 high speed gears, and while they were at it, I had them put a few upgrades into it:


Upgraded/changed parts:

·        ASG ultimate 16:1 high speed gears

·        Laylax Promethius 280mm 6.03mm tightbore inner barrel (stainless steel)

·        Promethius purple bucking (flat hopped)

·        New pistol grip (fits hand much more snugly than the original)

·        Rear wired to deans connection for faster trigger response

·        Uses 11.1v LiPO

·        Increased power spring (may be > 330FPS as I use it as a DMR these days)

·        Chrome flash hider

·        Red/green dot and flick up iron sights

·        3x small Weaver rails added to Keymod handguard (Under, and both sides for grips, torches lasers etc.)




Comes complete with Chris Hobbs/”GearTech” commissioned COD4 “Fall” style paint job (some came away on the handguard during a VERY wet skirmish day - as shown in photos. I’ve since applied a thin layer of clear lacquer to protect the remainder).

ASPUK also serviced the gun and shimmed the gearbox in January (I do have a certificate somewhere)

Comes with:

·        Two hi-cap mags featuring the same paint job

·        2x 11.1v LiPO bateries

·        Original box

·        Original gears

·        Original spring, should you need to reduce power

Looking for £400 O.V.N.O.
