Flechette firearms refer to weapons that fire flechettes, which are small, dart-like projectiles designed for increased penetration and accuracy. Flechettes are typically long, slender metal darts that can be aerodynamic and are often used in shotgun shells or specialized military ammunition. In the context of firearms, flechette rounds can be used in smoothbore and rifled barrels, with the potential to provide a higher projectile velocity and reduced drag compared to traditional shot.
