ABSTRACT:
A archery device comprising a tubular shaft having a slidable inertial member trapped within the bore extending between the injection molded resilient notch plug conforming with the perimeters of the bore and the notch in the string receiving end and the transversaly positioned back wall of the vented projectile chamber secured within the bore at the forward end of the shaft. Slidable inertial member comprises an elongated metallic weight having at each end an annular goove fitted with a soft flexible foam pad therein and frictionally engaging the interior wall of the tubular shaft. Projectile chamber in the forward end of the shaft is provided with a detachable containment cover having a three sided configuration that fits on the forward end of the shaft with the shaft in longitudinal alignment between the opposing sides of the cover while the closed end of the cover caps the exit end of the projectile chamber in the forward end of the shaft. The longer of the two opposing sides of the cover has at its end a flange bent at a ninety degree angle to facilitate the detachment of the cover by making contact with the bow as the arrow is drawn to near its full length prior to its release thus forcing the cover to leave the shaft. Cover is secured to the shaft by an elastic band transversaly encompassing the cover and shaft while seated in corresponding slots formed in the edges of the opposing sides of the cover.
