That's what I would expect as well however it looks exactly like the DD Mk 18 Rail which is 9.5". Then also DD Omega Rail 9.0" is 8.88" and DDM4 9" is actually 9.325" so you get all kinds of length. I need to know the length so that it fits in between the receiver & front sight post.
wonder if it's worth messaging a shop like Patrol Base? they're usually pretty helpful, people ask questions like that when they showcase certain stuff
