It would be exactly 384fps.  There is no real way to tell. Every gun is going to have different results. I did this same set up and mine shot 130+/- lol. I never could get it to run properly. With only the barrel it was pushing 500 fps.

When you said 384fps, at what temperature was that? Right now it's 110 degrees outside...

I guess what I really want to ask is... How can I keep it at 400fps with a 363 mm tbb?

I was being sarcastic when I threw that number out there. Don't forget that just by using heavier bb's to get under 400fps is a no go. It is extremely dangerous and can really get someone hurt. Especially in a CQB arena. All fps limits are based on using .20's. My G&P aeg is shooting 395ish with .28's. So with .20's it will be closer to around 430-440. I will install my barrel again and get my hands on a chrono to see exactly what it is running.

Thanks for doing that Huntsman!!!!

I just want an increase in accuracy and tighter groupings. I will be fielding my MP7 and not CQB. Should I just stay with stock right now? Like you said, every gun shoots different.

I have had great success with the stock configuration. they make a tight bore barrel that is only marginally longer. That may be of interest for you.

Were can I find this "marginally longer" barrel?

If I decide with the 190 mm, what would be my fps? With what bbs? And what suppressor can I use that will be flushed at the tip, with the inner barrel?

Someone who has used the dangerwerx valve would have to chime in on that. The 190mm barrel doesn't even go past the flash hider so a suppressor isn't necessary. It will only raise your fps a small amount if it does at all.

How about my groupings? I could have the 363 mm cut?
