This replica is a high quality built based on the M4 platform, with a very modern twist, if you want a rifle which looks cool as well as performs great on a budget, you've come to the right place. The replica features everything you would expect from a modern weapon, with 20mm RIS / RAS Rails for attaching a wide range of aftermarket parts and accessories, as well as MLOK sections for fitting the latest Airsoft parts to hit the market.

Full description


The replica is constructed mainly from nylon re-enforced polymer, with alloy parts in all the right places for strength. The rifle features a polymer hand guard, receiver, pistol grip, sights, stock, and buffer tube, alloy outer barrel, sling point and internal parts. The rifle has a high quality finish, and looks highly realistic at all distances and features a highly advanced hand guard with compatibility for 20mm RIS / RAS as well as M-LOK attachments.

Externally the replica features a huge top rail, forward rail points, as well as modular rail points. The top of the hand guard and receiver feature a lined up 20mm RIS / RAS rail allowing for huge sight and scope setups, allowing you to either go for a large magnified optic, or an advanced holographic and magnifier setup. The front of the hand guard features four point 1.5'' 20mm RIS / RAS sections at the 3, 6, and 9 o'clock positions to allow the user to attach torches and lasers to taste. For the majority of the rail, at the 3,6 and 9 o'clock positions the hand guard features MLOK panels, allowing you to attach various MLOK accessories at any position you like, with MLOK being the latest and most advanced attachment method to date. Fancy a new fore-grip, a torch, lasers, or even launchers? You'll easily find a 20mm or MLOK attachment to fix, allowing you to go wild with the way your replica looks and functions. If you want to attach a 20mm attachment to an MLOK area you can always purchase MLOK to 20mm rail adaptors as required. If you're feeling fancy you could also replace the hand-guard in the future to give the gun a new or refreshed look.

To the rear of the replica is an adjustable 6 position stock which doubles up as the battery compartment, and allows up to a 9.6v Ni-Mh crane stock battery to be fit, meaning a lot of aftermarket upgrade LiPo will also fit thanks to the generous amount of space. To the rear the butt plate is also rubberised to prevent slippage, and there are also slots for QD Sling Loop mounts to allow you to attach Slings to carry the replica easily.

Looking to go tactical? The flash hider of the replica can be removed to reveal a 14mm CCW thread, the most common type of barrel in Airsoft, meaning a huge range of Silencers, Suppressors and Tracer units can be affixed to the replica. If you want to give your replica a more tactical look you can attach a suppressor, or if you want to see your BBs as they travel through the air at night you can attach a tracer unit and use tracer BB's to put on a light show.

The replica features an adjustable hop-up unit for range and accuracy. The hop-up works by having a small patch of rubber the BB comes into contact with before it travels down the barrel, this causes the BB to spin and displace the air around it to add range and accuracy to shots. The hop-up is fully adjustable to allow you to use a wide range of BB weights and types, and is adjusted via a radial adjuster making it easy to make tiny adjustments for a perfect tune.

Internally the replica features a rear wired V2 gearbox, meaning that the batteries are stored in the rear of the replica, and the gun is powered by a motor allowing the replica to fire in semi and fully automatic firing modes no matter the weather. If tinkering is your thing then there is an absolutely huge selection of aftermarket parts and upgrades thanks to the replica's inclusion of a V2 gearbox, the most common type of gearbox on the market. If power is an issue, then the replica features a quick change spring system allowing you to quickly swap out the spring for a more powerful or weaker spring without having to completely disassemble the gearbox. The replica also features low-resistance wiring to ensure maximum performance and lifespan of the batteries used. The upgrades don't stop there, the replica also features a 6.04mm tight-bore barrel for increased range and accuracy when using heavier weight BBs.

This rifle is perfect for any Airsoft Skirmisher new or old, making an extremely potent beginner Airsoft gun, or great backup replica for a seasoned veteran. The replica has plenty of room for internal upgrades, and looks beautiful, with plenty of external compatibility for visual and tactical upgrades making it a perfect starter replica.

Special Instructions

Please note that the QD Mount holes are mock mount holes, and are not compatible with actual QD Mount Loops.

Please note that the battery and charger that come with the gun, although higher quality than the usual free gift battery and charger, should be replaced as soon as possible with higher quality after market alternatives. 

The charger is auto-stop, which means that it will stop charging when the battery is full, this is great, because usually when you get a gift charger they do not and can damage the batter. You can keep hold of this charger to use in a pinch, but we would still recommend replacing it.

The battery is great compared to the usual battery you get as a free gift with Airsoft replica. The battery has a 1600mAh capacity, which is larger than the usual 1100-1300 battery you get. This means that it should last as long as most other aftermarket battery. We would suggest replacing it as the quality of the cells may not be as good as other alternatives, but is definitely worth keeping as a spare or backup battery.
