Abstract: An actuator assembly includes a piston chamber assembly having a piston chamber and a pin receiving tube extending from the piston chamber. A gas transfer pin has a first end inserted in the pin receiving tube and a second end received in a rifle sight alignment bore. The gas transfer pin has a longitudinal bore in communication with the piston chamber. A piston member is slidably received in the piston chamber and includes a piston body with a piston member extension tube. The piston body includes a raised piston portion having piston rings, and a ring divider slot positioned between the piston rings. A rod assembly has a rod engagement end received in a piston member extension tube receiving bore. A piston clip has an arm extending through both the rod engagement end and the piston member extension tube connecting the rod assembly and piston member and a spiral end.

Abstract: An aerodynamically and structurally superior, fixed-blade hunting arrowhead providing higher penetration coupled with a structurally sound, non-deflecting, blade-cutting area to take down wild game quickly and humanely. The assembly includes the ferrule, main blade, and sub-blade, wherein the unitary ferrule has a machined structure that holds and reinforces the blade units as well as incorporates a concave-faceted cutting tip, blade-location channels, cavities for blade snap retention, and rearmost threaded portion for attachment to a standard arrow insert. The main blade is a one-piece element which incorporates two forward-cutting blades and two rear blades, as well as rearmost anchoring projections attaching the blade to the ferrule. The sub-blade is a one-piece element positioned perpendicular to the main blade and is retained in the same manner as the main blade by integrated projections snapping into cavities within the ferrule.

Abstract: An Archery Manufacturers & Merchants Organization (AMO) standards-based, arrow assembly, weight-and-length enhancer for archers and/or bowhunters is disclosed, which provides a fully compatible, standards-based way to increase the length and/or weight of the front of the arrow assembly by simply unscrewing the existing arrowhead from the insert of the arrow and screwing this enhancer between the two components. By having internal threads on the device located directly within the outer shank area of the enhancer, the strength is increased due to a decrease in leverage, and the overall length of the assembly is kept to a minimum.
