power mods

I just got all my parts in from Mellon Air to do my 1322 conversion. I didn't even think of it when I ordered the parts, but is there anyone that I can send my FT valve to that will do the power mods to the valve?

I can probably do it, just a little apprehensive about tearing it open and doing the tweaks and all. I don't want the ridiculous power, just a little more for .22 shooting.

Or if any of you know of a good tutorial with pics (they help me a lot) I would feel better about trying myself.

Thanx,

Matt
