ADMIRAL MK-4 CS

Extended-capacity professional CS tear gas spray for prolonged law enforcement operations.

ADMIRAL MK-4 CS delivers 50% more operational capacity than the MK-3 CS, designed for extended-duration interventions, reinforced patrols and team deployments. Built in close collaboration with government agencies and security organizations, it meets the latest operational and regulatory standards. Its 90 ml format and safety flap actuator deliver simple, controlled use under stress, while the rugged build is engineered for repeated tactical deployment in real-world conditions. CS chemistry is particularly suited to standard intervention scenarios, multi-subject engagements and operational contexts where a strong respiratory and lachrymatory effect is required.

With an effective range of up to 4 meters (13 ft), MK-4 CS neutralizes a threat at safe distance — preventing physical contact and minimizing injury risk. Its semi-ballistic stream is designed for accurate, directional delivery with reduced cross-contamination, a critical advantage in confined spaces, vehicles or close-quarter interventions. The extended capacity provides up to 18 individual bursts of 1 second, supporting multiple engagements or sequential subjects without canister change.

The active ingredient is CS gas (orthochlorobenzylidene malononitrile), the standard chemical irritant used by international law enforcement for crowd management and tactical interventions. Unlike OC pepper sprays, CS is a synthetic compound with predictable, well-characterized effects — making it the agent of choice for standardized operational protocols and post-intervention reporting.

Incapacitating effect

On contact, CS immediately triggers intense lachrymation, strong respiratory irritation, involuntary eye closure and disorientation. The subject is incapacitated for 15 to 30 minutes, allowing the operator to control the situation, complete intervention procedures and call for backup if needed. CS is most effective on subjects in standard physiological states; for engagements involving subjects potentially under the influence of alcohol, drugs or medication, OC formulations (MK-4 OC) or combined OCS formulations (MK-4 OCS) may be considered.

ADMIRAL ecosystem

MK-4 CS is part of the ADMIRAL professional ecosystem. For training and operator certification, an inert version is available as ADMIRAL ZERO with identical format, weight and ballistics. After deployment, ADMIRAL RESCUE-OCS provides rapid flushing for affected skin areas — supporting both team recovery and post-intervention duty of care.

Operational deployment

The semi-ballistic jet is designed for directional engagement at the target's facial area, with reduced cross-contamination in the immediate surroundings. The 90 ml capacity supports prolonged engagement scenarios and sequential subjects without operational interruption. Operators are advised to step aside after deployment, as the subject may continue forward despite involuntary eye closure. Use strictly reserved for situations of real danger. Operator training is mandatory — see ADMIRAL ZERO for inert training sprays with identical ballistics. Use must comply with applicable laws and authorized operator status.
