I bought this brand new in June/July last year and had it delivered straight to Luke at Negative Airsoft.

He fitted a Perun MOSFET, Warhead Base motor, one of his nozzles, a Novritsch flat trigger, a long with various other bits to optimise the performance and reliability. This is of course shimmed beautifully too.

Later on I added a Maple Leaf Macron and Omega nub to perfectly match the 310mm Maple Leaf 6.02 inner barrel, which runs through the outer barrel extension and a more powerful spring to bring me to 1.05J with 0.28g's. Additionally it has an aftermarket rotary hop unit, to better match the nozzle. As you can see from the chrono results, this all results in very consistent shooting, right around the perfect power output for most sites.  

As you can perhaps imagine, it's subsequently got great range and accuracy. It's also super snappy/responsive and sounds great too.

The fully licensed externals of this RIF are made to a very high standard, IMO it feels a lot nicer than the Specna Arms MK18.

It also comes with a very easy quick change spring system.

I've only skirmished it for one half-day. So it's in excellent condition inside and out. If I had to think of any slight negatives, it's that I unfortunately caught the wires when putting the buttstock back on, but these were professionally repaired by my local retailer. Also, when they were working on it, a tab came off the Warhead, so was soldered back on.

Stated price includes PayPal fees and tracked courier.
