Abstract: An arrow penetrator brake assembly mounted on a conventional hunting arrow assembly and operable to provide a braking function when passing through game or into a brush area. The arrow penetrator brake assembly includes 1) a main support bushing membr; 2) a grabber spring member mounted on the main support bushing member and 3) a brake control member mounted about a main arrow shaft and engagable with the main support bushing member to achieve an adjustable braking function. The main support bushing member includes a spring retainer section for receiving and holding the grabber spring assembly. Impact force is transferred from the grabber spring assembly to the main support bushing member which engages the brake control member to achieve a controlled rearward axial movement of the arrow penetrator brake assembly on the main arrow shaft.
