Phew where do I start?....
Reg,bolt,feedneck,trigger,on/off asa,breech,firing can, body kit,barrel,board, basically the whole gun
This is an extremely quite gun
Unless you want to spend 300+ on upgrades get a better gun
This is an "ok" gun for those who just want to play paintball once in a while and dont want to spend a lot of money on high end guns. This is a reliable gun even if it's all stock. It's extremely quiet compared to the Spyders and Tippmans. It's even more quite than my 05 Ego, There is barely any kick. The cons for this gun is that you need to upgrade ALOT to get it running in the tournament level. But once you upgraded it the ION absolutely rips, My ion can wipe my Ego anyday, it's super quite and really accurate with the freak kit.
Great Beginner gun But a tournament level gun upgraded
