You can find them both at airsoftparts.ca and read about them in the small description - the blue actually states its supposed to be used for 350fps and lower.

During my several year long quest in hop up unit selection, i've actually read that those mad bulls cause jams and double feeding all over the place - mind you this boils down to your own user perspective and results will always vary.

Edit: My suggestion for 400fps and above - pair this bad boy with some teflon tape (if needed) and you're golden.

The best investment I have ever made in airsoft is buying my own chrono because i do my own gun work. I can check things twice, thrice whatever you want.

I ALWAYS tear down my hop up units twice - once without teflon tape, once with. Sometimes it will fit sometimes it wont, not all inner barrels have the same diameter (such as the mad bull python) and some hop up sleeves are thicker than others - therefore not allowing the teflon tape and/or creating air leak.
Interesting, because I installed one of those madbulls in my girl friends gun and she had two jams early in the game before they finally stopped jamming. I guess we'll see how it works at the next game. It's a 370 fps set up vs a 430 fps, however.
