Would you recommend an FD-PCP for someone who's never shot/worked a PCP before?

yep, that's about all you need... there are other things to tinker with but that will get you going real nice. if you need any help just holler, we're all right here and happy to help.

also use fill pressure to adjust string...some like a lower or slightly higher fill pressure, every one is a bit different...

Mike, can you tell us the port sizes on the 'power tuned' GEN II? 

I would like to tune this gun for absolute max power and use a (reverse mount) bottle to extend shot count a little -possibly only enough for a PRod magazine (or even two, but only if power doesn't suffer.)

It's also a little daunting to a however well studied (and metal fabrication experienced) novice
to embark on 'tinkering' without a backup valve and a spare fill plug&cap.

And to even be able to assess shot count and deviation (never mind to safely know that the gun is not just "probably" empty before opening it up,) the check valve needs to be moved for a downstream gauge, which I personally already have started to consider absolutely essential.

Since FDPCP valves are understandably at a premium, can we at least convert QB valves by imitating what you did to our XS60C PDP valves (or try our mods on it?)
How well would, say, a commercially modded QB/AR valve (XP etc) FIT?
Can the end plug on a "spare parts" XS/QB plug/cap (from UknowWhere) seal at HPA pressure?

[mikeiniowa]

the complete QB valve will fit, max. port size is 5mm any more and a .22 pellet falls in, for .177 use 4mm. Only use a brass type cap, plastic will work but is kind of iffy...have one being tested but don't trust the plastic to hold the nipple

Thank you Mike - as always!
