The extension should be forward of the edge of the receiver if there is any break in the two. You want the bullet tip to "jump" the gap.
There is a slight set back between the receiver and the extension here, this is what you want to see. There is more of a gap than it looks, the cerakote makes it hard to see as well as I'd hoped.

Yea all mine look like that and understand that's how they should look.
Guess I didn't word my opening post correctly.
What I was meaning is did anyone research are try to develop a wider feed ramp area in the barrels extention dinking the grendel with its much wider bullet profile compared too 223/556.
Figured Bill or somebody had but Google fuu is not strong with me tonight couldn't find any intel.
