Abstract
A flechette is disclosed comprising a rod-shaped steel body having a blunt generally conical penetrating point, a separate resinous plastic fin component securely mounted on the rear end portion of the body, and a generally conical gradually tapering resinous plastic nose piece securely mounted on the penetrating point for reducing air drag when the flechette is fired at high velocity. Interlocking annular flanges are formed on the penetrating point and the nose piece for securing the nose piece to the body.
