When I first got the ion i liked it alot, it was and still is my first electric gun. Once I got it the first upgrades were the Q-lock and a red body kit. Now it worked pretty good but do not use anti-syphoned co2 no matter what people say. In the end your gun will hate you if you use anti-syphon. So i switched to compressed air. Now the thing with this gun is the trigger and the standard board aren't so good for walking and changing modes and settings. So i baught the t-board along with some parts to make it keep up with the board. But the thing with this gun is when you start adding parts to it,the reliability CAN go down unless you really really really lube the bolt good. But it seems as though it works fine just shooting around for fun,but when you go to acctually play it screws up on you.
Conclusion:
But that isn't always the case, the only reason i emphasize is because it would happen at the worst of times but only has happend 3 or 4 times. the past 5 times i've played it's worked perfectly. So basically when this gun is working good and your using it when you play, it's a sick gun and acctually rips.
