For sale is my Tokyo Marui M4A1 RIS (rail interface system) AEG (automatic electric gun)

The gun is in excellent condition and has been converted to a replica of a Knights Armament SR16 using the following parts:
- King Arms metal body with full trademarks - beautiful receiver that cost me £110 on its own. This has a locking bolt cover to access the hop up, which is released using the bolt release. It also has spring detents on the body pins.
- G&P M16A2 black stock - this is great for holding larger batteries, which is not so necessary nowadays since lipo batteries have come along, but it's big enough for a NIMH if you want to run one. This cost me about £40 and is in good condition. Easily changed to sliding stock if you prefer.

It has also has the following upgrades:
- Dboys high torque motor
- New trigger switch with new wiring and deans connector for battery
- G&P ported piston head
- Guarder air nozzle
- metal bushings

The gun shoots really nice with about 280fps although I haven't chrono'd the gun in ages.
The internals of the gun are like new and I've just serviced it and cleaned the gearbox up and regressed everything aswell as re-shimming all the gears so theyre nice and quiet.
If you wanted more FPS, I'd suggest an ASG ultimate cylinder head, nozzle and M100 spring, which would set you back about £25 and would get you around 325FPS.

If the buyer pays the asking price and I still have them I will throw in a viper tactical 3 point sling that's perfect for this gun and I will fit a guarder tightbore barrel and JBU hop up bucking. Ill also throw in a couple mid cap mags and possibly a red dot sight.
I've probably got a 7.4V lipo kicking around and the original box too which is quite valuable these days.

I've priced it at £220 which is less than I'd get for it in parts, there's a brand new one on eBay Japan for £365 but obviously is plastic bodied without upgrades.
