To anyone who can answer:
I'm considering doing this in a stock tm MP5 RAS with a 140mm (I think) king arms silencer, and a M4 twist barrel.
What other upgrades should I be looking at to keep it working properly?
Is there is a noticable improvment, or should I just go with the stock length twist barrel and upgrade the internals to 330?

Just a toss in, my TM MP5 was shooting 365fps with the stock 229mm inner barrel, and because I had the SD front end on it, I decided to cut a custom length that'd fit inside the SD supressor, settled on a 330mm length cut out of my stock M24 barrel I replaced a couple years ago with a tightbore. Next time I chronied it, my fps had gone up to 387fps. So a rough guess, 100mm = 30fps. Not a set in stone method, but a very rough one anyways.
