I'm thinking of upgrading my M4 to around 320-330 fps. The parts I'm thinking of using are as follows; SP100 spring, Guarder steel bushing set ver.2/ver.3, Guarder Shim Set. I assume my ROF will drop if I still use my 8.4 battery, should I go with a 9.6? The white grease and silicon lubricant I have in my garage, the stuff is from Crappy Tire. Is this setup ok or am I missing something important stuff?
