This isn't the Raven. The Raven was a design exercise by Alex Hodge which isn't (at present) going into production. The loader that Nick Slowiak is using is the new GI Sportz loader with inbuilt chrono.
Alex also didn't design the internals of the J4 Torque, that was Josh from J4 - although I believe Alex is helping the J4 guys with some of the external design.
