The FN 303® Less Lethal Launcher: The Right Level of Response

Nowadays, both armed forces and law enforcement officers all around the world have to face an increasing number of peacekeeping and law enforcement operations, where, very often, the use of lethal weapons is not always the most appropriate.

To meet these new evolutions, FN Herstal introduced the FN 303® Less Lethal Launcher in 2003. An effective way to strike the suspect from a distance.



  • Accuracy

    The FN 303® is extremely accurate at 25 meters and offers a very high probability of torso hits at 50 meters. It can be used at ranges up to 100 meters.
  • Efficiency

    The FN 303® guarantees a maximum effect on impact. The shock and pain caused by the impact instantly stop and neutralize the suspect.
  • Ease To Use

    Using compressed air to launch projectiles, the FN 303® gives no flash, very little sound and almost no recoil.

  • Multiple Engagements

    The FN 303® fires semi-auto from a 15-round magazine allowing rapid multiple engagements.


The FN 303® Less Lethal Launcher can be used in a very large number of situations such as:

  • Stopping an hostile but unarmed individual or group
  • Room extraction
  • Surveillance and protection of sensitive areas
  • and much more

System Description

The FN 303® has been specifically developed as a less lethal device and allows neutralization and seizure of suspects with maximum effectiveness and reduced risk. The FN 303® launcher consists of three main components: the less lethal launcher itself, a 15-round magazine and an air compressed bottle.


The lightweight polymer magazine of the FN 303® holds 15 projectiles and features a transparent cover to allow the operator to instantly verify both projectile type loaded and number of remaining shots.



The FN 303® projectile has been specifically designed to reduce the risk of penetrating injuries.

The primary effect of the projectile is trauma, capable of stopping and neutralizing the aggressor immediately. Secondary effects from the projectiles can be delivered via a chemical payload, such as a marking or an irritating effect, depending on mission requirements.

Most of the time, only one shot is enough to neutralize the suspect, which makes the FN 303® less lethal system really different from the other existing less lethal products.

The 18mm (.68"), 8.5 g weight projectiles utilise a fin stabilized polystyrene body and non-toxic bismuth forward payload to provide both a more accurate and greater effective range than the other less lethal systems.

The FN 303® projectile range includes five different types, featuring identical weight, identical ballistics and consequently, identical impact.
