The '''FN 303''' is a [[Semi-automatic firearm|semi-automatic]] [[less-lethal weapon|less-lethal]] [[riot gun]] designed and manufactured by [[Fabrique Nationale de Herstal]].

The FN 303 uses compressed air to fire [[projectile]]s from a 15-round drum magazine. It is designed to incapacitate the target through [[blunt trauma]] without causing critical injuries, and is most widely used for [[riot control]] and other kinds of combat where lethal weapons should be avoided.

The 303 can be fired from the shoulder using adjustable [[iron sight]]s, or it can be mounted in an under-barrel configuration on most [[assault rifle]]s when its stock assembly is removed (in this configuration, it is designated ''M303''). It also comes with a top-mounted [[Picatinny rail]] that can fit most commercial weapon accessories, such as [[telescopic sight]]s, [[Laser applications#Laser sight|laser sight]]s and [[tactical light]]s. FN markets its own set of accessories for the launcher, including tactical vests, slings, carrying bags, and gas compressors. It is accurate at distances up to {{convert|35|m|yd}}.

FN also produce a pistol variant, the FN 303-P, in the same caliber, using a seven-round magazine with a self-contained gas cartridge.<ref>{{Cite web |title=FN 303®-P |url=https://fnamerica.com/products/less-lethal/fn-303-p/ |access-date=2020-06-15 |publisher=FN |language=en-US}}</ref>
