Yup, I see where i was confused.The launchers Colin is referring to are specifically chambered in a proprietary "37mm Rebated Rim" caliber which has only ever been loaded for low-impact charges like flares, riot batons, pepperballs and other less-lethals. Hence why these have thus far escaped the 2020 OIC as they were not considered standard firearms to begin with.
The OIC is referring to the "37mm Rimmed"
Whereas the Exempted launchers are "37mm Rebated Rim"
