Myself and a few others have installed Prommy 407mm barrels. On my M4A1 (same barrel length), the inner barrel extends about 3/8" into the flash hider. Working out very well so far.

I have the 407.  Beaware if you use an aftermarket flash hider that it might push the barrel when fully tightened depending on the flash hider.  The stock one doesn't do this, btw.
