So... tried to do some homework, but by no means am I a tech so I thought I better get some help here. If possible, I want to buy all parts in one order, which is why I've got links from redwolf so far, which I've ordered from before without issue. Any suggestions on retailers would be appreciated too.

I am going for a P90 that will work fairly well for outdoor use (yes, I know, odd isn't it?). That means I want to take it to 380-430fps range, which seems to be the moderate competitive range out here. So far I have put an extended barrel into it, which is hidden in the TR's stock silencer. I noticed that the extended barrel reduced the fps a fair amount as well. I had a retailer in Calgary shim up the gearbox and add metal bushings. In terms of reliability, its working well, but it is shooting under 300fps. The Systema M120S spring is pegged at approximately 422fps on the spring chart on this website.

EDIT: Parts list was totally off.

Do I need all the parts I chose, do I need more, are there better alternatives?
