The FN 303 Mk2 is updated to be more accurate and run longer.

If 2020 taught us anything, it’s that the world, at the drop of a hat, can descend into chaos. So the timing couldn’t be better on the release of the updated FN 303 Mk2 Less Lethal Launcher. The Mk2 improves upon FN’s original 303 system, firing fin-stabilized .68-caliber projectiles.

FN 303 Mk2 Less Lethal Launcher

“From the first release of the FN 303 Less Lethal launcher in the early 2000s to the release of the Mk 2 variant today, FN has been at the forefront of the ever-changing landscape of policing, developing innovative solutions for officers and agencies,” said Charles “Bucky” Mills, Sr. Director, Law Enforcement and Federal Sales for FN America, LLC. “Updates in the FN 303 Mk2 include fully adjustable sights for ease of zeroing, and upgrades to the air operating system that double the service life of the launcher and reduce required maintenance.”

The 303 Mk2 utilizes a lightweight, rugged polymer. A compressed CO2 air tank drives the system. The revised launcher delivers pin-point accuracy out to 50 yards, according to FN. New, adjustable flip-up metal sights get officers on target. Meanwhile, a MIL-STD 1913 top rail provides for mounting optical or red dot sights. The optimized operating system doubles the service life of the FN 303 Mk2, allowing 5,000 projectiles fired before first required routine maintenance. It reduces armor maintenance requirements while maintaining operational readiness.

The fin-stabilized FN 303 projectile comes in several inert, marking and irritant forms.

The .68-caliber 303 projectiles maintain accuracy and maximum effectiveness and safety, according to FN. Officers can quickly change projectiles from inert, marking impact or irritant. The clear, rear magazine cover enables officers to visually inspect projectile type and count in the magazine. For even more info, please visit
