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 clear rear cover to allow the operator to instantly verify both projectile type loaded and number of shots remaining at a glance.
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 directly. 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 (.68mm), 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 other less lethal systems.
The FN 303™ projectile range includes five different types, featuring identical weight, identical ballistics and consequently, identical impact.
