I'm amazed by this gun, It's a cocker and even though I have had a thing against cockers it has had no problems, shoots faster than the timmys and trixes on my team and when comparing accuracy it shoots darts, ball on ball, especially with the race kit.
Check it Uni-mount
Accurate, great range, fast, many modes, tiny.
Back block set screw
the gun easily outperforms my NME and the only problem I have has it loosing the bolt pin. It sometimes catches on my pocket so instead of being on my gun it ends up in my pocket. Whatever I fixed the problem.
The gun is extremely small and light, though there is a small amount of kick once you are used to it you can barely feel it.
set screw in back block must be lock tighted down.
great gun, it is very expensive but check out pbnation I got mine with a race kit for $940
