FN 303® Mk2 Less Lethal Launcher

Available for law enforcement and military.

FN is the world leader in developing law enforcement technology and training, setting the global standard of less lethal technology with its FN 303® Less Lethal Launcher. Answering requests from law enforcement to reduce department armorer maintenance and extend the service life of the FN 303 less lethal launcher, the FN 303 Mk2’s improved operating system doubles its service life and cuts armorer maintenance in half.

Built from lightweight, rugged polymer and driven by a compressed CO2 air tank, the FN 303® Mk2 upgrades FN’s less lethal technology for today’s officers, delivering increased accuracy with new, adjustable flip up metal sights and a MIL-STD 1913 top rail for optical or red dot sights. The fin-stabilized projectiles deliver optimum accuracy with maximum effectiveness and safety. Officers can quickly change from inert, marking, impact or irritant projectiles, with a clear view of the projectile type and remaining count in the magazine.
