Spyder Acs

[killerpinecone]

Hello I have a spyder electra acs with a 14" SP teardrop barrel and a 32* spring kit and I was wondering what high flow expansion chamber or regulator to get and what other mods (performance wise) i should get to make my gun shoot harder/smoother. I am just trying to kill my freind with an ion he said that spyders suck so I need to hurt him with the electra . Also if yall have any pics to post of a modded electra acs please post
