Opportunity: Night Shoot #2 Carbon fiber vs Metal on the Rubato
The Rubato is our entry-level Pistol/PCC can. Its designed from top-to bottom to be modular, with HUB compatibility and a replaceable stack and end-cap.

The base model comes with an FDM Carbon Fiber stack with a life expectancy of a couple of hundred rounds. As they cost a few dollars to manufacture, we are happy to send you replacement stacks for the rest of your life, but some people with more agressive shooting schedules prefer a permanent configuration, so we offer two different metal stacks: One for FRT/Full auto on a fixed barrel/PCC (Full Metal Edition™) and a lightweight titanium one (Rubato: Space) thats perfect for handguns with a booster.
Heres the thing:
We have unverified reports (and our own experience) that seem to indicate that the CF stack is not only quieter but also runs cooler than the metal ones, and we'd like to prove it.

Whats needed:
We are looking for a location, preferably in central FL, where we can shoot low-light and collect video/images/audio comparing the three different Rubato stacks. A Db-meter of decent quality and thermal imaging will be necessary.
If you own a Rubato, have this equipment and are willing to conduct the testing and share the results, we can provide you with heavily discounted materials and credit for your work.
Current status:
We have everything that we need for this one aside from a location and thermal imaging. We'd love to get this one knocked out before GOALS (July 31)
