TM M4 (Version 2 Gearbox)

[wobbit]

I want to upgrade my TM M4 (v2) to 328-350fps. I know I need a new m100 spring (http://www.zerooneairsoft.com/produc...oducts_id=2786). I also have researched that I need some bushings, but I’m unsure which ones to get.

Could someone post a link to the correct bushings for me?

I was considering buying a tighter barrel, but again, I’m unsure which one to get.

Do I need to do anything else?

Sorry if this has been answered a lot before but I couldn't find what I needed from a search
