US Patent 7909714 Rear mounted penetration limiter for bow-fired projectiles

A rear mounted penetration limiter for bow-fired projectiles for use in combination with a projectile and a nock, wherein said projectile is an arrow or a crossbow bolt, said penetration limiter comprising an attachment component, a nock securing component, and an engagement component having one or more engagement members, with said penetration limiter suitably adapted to limit the penetration of the projectile through a game animal once the front end of the projectile has struck and passed through the game animal, thereby allowing the creation of an exit wound while retaining the projectile within the game animal. In one embodiment the penetration limiter is adapted to detach from the projectile, remaining secured thereto by a short tether, thereby allowing the detached penetration limiter to reorient itself within the game animal to create greater drag on the projectile.
