If the grooves on the underside of the rail lock into the splines on the barrel nut, then the length of the rail should be correct to lock it into the front handguard ring.

Is this what's happening here?

I measured the handguards from my Bushmaster XM15E2S and they are 6 5/8". The stock handguards from my PTWs are 6 5/8" as well.

I looked at both as a comparison for fit at the points where the meet the barrel nut and the front ring. They are so close as to be virtually indistinguishable. The Bushmaster ones have a little "tit" to allow for a more snug fit, while PTW ones are smooth around the circumference where they fit in the front handguard ring.
