i dunno it didn't really seem like it needed any, maybe tadao or virtue when it comes out.
100 psi operating pressure
very little kick
I didn't like the feel that much thats subjective though.
I had heard a lot about these markers so when someone showed up at my field with one i jumped on the opportunity to shoot a couple pods through it. This gun is very light, i had just test fired an 08 ego just before i shot this and the gun didn't feel much heavier. I turned the gun on and ripped and entire halo effortlessly the marker is very fast and has very little kick (slightly less than my dm4 and pm6). What impressed me most about this marker though, is how ridiculously consistent it was, i was getting +-2 over the chrono and from 75 feet away it was putting ball on ball, there was one mark about 4-5 inches across from a whole pod of paint on the wall. It is the combination of the consistency over the chrono and the lack of kick that makes this marker truly deadly. Though i was very impressed by the consistency and lack of kick, this marker almost had too little kick, it had no feel to it, i barely knew i was shooting, this gun might take some getting used to and feel is more of personal thing so i didn't count this in the overall score.
If you get the chance, shoot one for yourself, this marker is revolutionary in its lack of kick and consistency.
