The First Defense OC/CS MK-2 Stream Aerosol from Defense Technology (part no. 1030658) is a duty-belt OC/CS pepper spray with a grey-banded canister and a stream delivery method. The 1 oz MK-2 is an ideal size for patrol officers to wear on a duty belt, and it delivers 7-10 short bursts at an effective range of 10-12 ft. The stream pattern prioritizes standoff over spread. The formulation combines OC with CS and is not EDW safe. It suits daily carry for patrol and security work.
