The Geissele Maritime Bolt Catch works with Mil-Spec dimension AR15's and may not be compatible with Billet receivers according to the manufacturer. So if your AR9 is Mil-Spec dimensions it might work.
I took a chance and ordered it. It did not work on my AR-9. I have a Spikes Tactical lower with a PSA upper and a Gen-4 BCG from PSA. It did not raise high enough to catch the bolt. It was close and would start to catch but ultimately I could not lock my bolt back. Will just save as a back up part for my AR-15.
