I too had replied on Facebook but here is my rocket launcher and I’d say 500 max but willing to negotiate price with them gladly.
construction is EVA with cardboard tubes and some wood dowels under the handle into the tube. SPNKr is 1:1 scaling on most it accurate for freehand work.
It does not operate and is one solid prop but light. Maybe 5lbs max.
SPNKr is ready to ship ASAP
