So its been about a week since i watched boobiem4h's videos on the lm4 and i thought hey pistols have rocket valves too. So i just had time take it out. Now my recent recoil modhad reduced my fps because it takes more blowback the slide.  So my question to you all is where and how much shaving should i do. also should i do anything to the rocket valve spring.

Fps right now is 280 w/ .2g

UPDATE: Shaved down the bottom end. Still no luck with FPS increase. Still i a work in progress.

I may have some crappy G&G .2g though becuase when i was shooting the KSC .25g it was shooting 260fps and with the .20g shooting 280. Doesnt make sence to me.

KWA LM4 shot between 395-415 with the .20 and 380 with the .25

so from now on im going to chrono with the .25 grams and go from there.
