ion, warrior feed neck, cp on/off, cp 1.5 inch razor drop and evlution 3
Fast, comes with z-board and better battery life.
None i love it!
This thing is awsome. Everyone should get it. Its fast and can keep up with any gun get one. But i forgot to menchin that the shell is the same as the evo 2 and 1. But the best parts are is it its 23bps and comes with the z-board. Also why spend $100 when u can get a hopper faster then it for like $80-90.
