I'd say Cinder used her Aura. Ren's defensive Aura manifested as a bunch of circle ripples. Cinder's Aura ripple was just colored differently.

Speaking of guns, I recall Monty stated in the DVD commentary (citation needed) that everyone is using Dust as their ammo. Whether that means they literally use Dust bullets or as gunpowder or both still needs to be answered by that Dust-centric episode that needs to exist.
