Ammunition cartridge comprising a rigid casing including a tubular sleeve and a base closing an end of the casing, a projectile mounted at another end of the casing, a propellant charge contained inside the casing, and an ignition device. The ignition device comprises an ignition charge arranged to ignite the propellant charge at a point of ignition distal from the base and proximal the projectile.

When combined with a variety of shafts of various lengths, this unit will create pistol crossbow bolts, crossbow bolts and archery arrows of various sizes used for recreational shooting, competition shooting, small game hunting and archery fishing. These bolts or arrows can be use with pistol crossbows, crossbows and archery bows or any other device used to project said projectiles. This seven and one half inch fletch unit is a solid one piece unit made of a strong but, light weight plastic compound. It has a NOCK to hold the bow string in place. It has two FLAT WINGS and a stabilizing TAIL which creates an accurate and stable bolt or arrow flight. No other fletch unit has flat wings with a tail. These features allow the bolt or arrow to be easily viewed in flight. This also allows this bolt or arrow to be used for competition shooting because these projectiles can be easily located, scored and then retrieved from any type competition target. This Morris 80 PLASTIC SHARK FLETCH UNIT has a smoothed dowel shaped end to accept almost any type of tubular shaft used for creating bolts or arrows.

When combined with a metal point, this ten inch plastic pistol crossbow bolt is designed to extend past the barrel of a pistol crossbow so it can be used for recreational shooting, competition shooting, small game hunting, pistol crossbow fishing and pistol crossbow scuba fishing. The main fault of the standard pistol crossbow bolt is they are less than seven inches in length and do not extend past the end of a pistol crossbow barrel. Therefore, their use is limited to target points and recreational shooting only. Other faults of the standard short pistol crossbow bolts are their high travel speed. They are very difficult to be viewed in flight, causing most bolts to be lost after one use. Also, their irretrievability from any commonly used target. Therefore, they cannot be found and scored in any type of shooting competition. This ten inch bolt is a solid one piece unit made of a strong but, light weight plastic compound. It has a NOCK to securely hold the bow string in place. Most bolts do not have a nock. it has two FLAT WINGS for elevation stabilizing which creates an accurate and stable bolt flight. No other bolt has this type of flat wings. These features allow this bolt to be easily viewed in flight. This also allows this bolt to be used for competition shooting because these bolts can be easily located, scored and then retrieved from any type competition target. The shaft has a THREADED TIP to accept almost any type metal point.

A strake may comprise a plate, wherein the plate extends between a forward end and an aft end along a first direction and the plate extends between a root end and a tip end along a second direction, a first tab extending from the root end of the plate, wherein a first fastening aperture is disposed in the first tab, and a second tab extending from the root end of the plate, wherein a second fastening aperture is disposed in the second tab.

A mechanism for attachment and detachment of a fixed or controllable airfoil to an airframe includes a base adapted for attachment to a root of the airfoil and a slot beam adapted for attachment along the airframe (e.g., parallel to the longitudinal X-axis of the airframe). The base includes a plurality of pins spaced along and held between parallel rails. The slot beam includes a plurality of slots arranged along the beam. Each slot has a lead-in portion to receive one of the plurality of pins and a longitudinally-oriented tapered portion (e.g., parallel to the longitudinal X-axis with a taper between 1 and 5 degrees) to engage the pin so that the base is seated in the slot beam to position the airfoil against the airframe in an XY plane. A pre-load mechanism is configured to apply a force along the X-axis to press the plurality of pins into the respective tapered portions to fix the base relative to the slot beam in six degrees of freedom (6 DOF).
