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. The fin component has an axial sleeve received around a rear pin portion of the body and securely retained thereon by annular flange and groove members on the sleeve and the rear pin portion. A modified flechette is disclosed having a separate, hardened steel penetrator component securely mounted on a reduced front pin member on the body by a press fit between the front pin member and a rearwardly opening bore in the penetrator component. A blunt conical penetrating point is formed on the penetrating component. Preferably, a gradually tapering, generally conical nose piece is securely mounted on the point of the penetrator component for reducing air drag. Interlocking annular flanges are provided on the nose piece and the penetrating point for securing them together.
