Ok, but "ok so these "air regulators" are rated 0-300 psi. CO2 tanks are higher than that, but if I never go above 10-12 these should still be ok yeah?" sounded like you might try running them as primaries.
You'll likely have to have the primary set for closer to 20 psi to have these secondaries provide regulated 10-12 psi at their outputs. Regulators have a minimum pressure differential and 5 psi is not atypical...
