1. What is the First Defense 7 MK-3 Stream OC Aerosol and how does it work?
This is a professional-grade pepper spray designed for personal and duty use. It deploys a focused stream of OC to help stop aggressive behavior at a distance. The stream pattern allows better aim and helps reduce blowback compared to fog or cone sprays.

2. How strong is the OC formula in this spray?
This model uses a .7% major capsaicinoids OC formula. That concentration is commonly used by law enforcement and security professionals because it provides strong, reliable effects without requiring excessive spray volume.

3. What is the effective range of the MK-3 stream spray?
The focused stream is effective at approximately 10 to 12 feet. This gives you space between you and a threat while maintaining accuracy.

4. How many uses will one canister provide?
A single MK-3 canister typically provides around 10 to 12 short bursts. Using brief, controlled bursts helps conserve spray and maintain effectiveness.

5. What should I do if accidental exposure occurs?
Move to fresh air immediately and avoid rubbing the affected area. Flush eyes and skin with cool water or saline if available. The effects are temporary but can feel intense. This product is intended for defensive use only.
