If an M4 barrel were cut & threaded to remove the M4 notch, would the barrel length come out to 10.5 inches?

I didn't think you could cut a chrome lined barrel and get a good crown on it.

Also how would you redo the gas system?

After labor costs and all, why not just buy a new barrel?
Yes, you can cut a chrome-lined barrel and get a good crown- no problem at all.
If you already own the barrel, cutting means you get the barrel you want for less than $100, instead of dropping another $250-$300 for it.
And to the OP, yes- the notch is eliminated and does not affect you with a cut to 10.5. As indicated above, you can even squeeze an 11.5 out (not sure about 12 without looking- I've not done one).
Edit - Missed the gas port - it's a pretty easy thing to open up the gas port. No other change is needed.
