Remage Nut in KRG Bravo?

Does anyone know if a Remage barrel nut will fit into a KRG Bravo chassis?

I’m considering rebarelling a Bergara B14 action that i have, which would involve the Remage nut onto a Preferred prefit barrel. I have a Bravo chassis with enclosed forend, but I’m struggling to visualize whether it would all fit inside.

Anyone with direct experience here?
