Abstract: A solid core less-lethal projectile is a frangible projectile which generally includes a hollow body, a solid core, a support structure, and a payload material. The hollow body can be formed by two hollow hemispherical bodies that are joined. The hollow body defines a closed interior cavity in which the core is contained. The support structure is disposed inside the cavity. The support structure can be a plurality of ribs configured to confine the core at a center of the cavity and space the core from the sidewalls of the hollow body. The ribs can protrude from an interior surface the hollow body to the core. The ribs can extend centripetally from the interior surface to the core. The payload material substantially fills the cavity around the core and the ribs. The core is configured to stabilize the projectile during flight toward a target. The core can be a spherical metallic ball.

Abstract: A dynamic sealing chamber magazine for an air gun carries multiple projectiles for the air gun and sequentially places each projectile in line with the bore of the gun while serving as a chamber for the projectile and gun. Each chamber of the magazine is configured to temporarily seal to an air orifice and barrel bore of the air gun upon firing. Each chamber includes a hole and two tubular sleeves therein. A pressurized gas released into a chamber when the chamber is aligned with the air orifice and barrel bore and the gun is fired pushes the sleeves apart from inside the chamber and compresses the sleeves into sealing engagement with opposing breech surfaces of the gun surrounding the air orifice and barrel bore. The sleeves decompress, unseal, and retract to a static position when the gas pressure decreases below the elastic potential energy of the sleeves.

Abstract: An air gun is provided with a magazine safety system and methods of making the air gun safe utilizing the magazine. The air gun includes a magazine well protrusion (e.g., floorplate) configured to extend into the magazine well when no magazine is properly inserted into and received in the magazine well. In the extended position, the protrusion prevents actuation of the main valve of the air gun. When a magazine is properly inserted into the magazine well, the protrusion is pushed into a recessed or depressed position by the interaction of the magazine with the magazine well such that the protrusion does not prevent actuation of the main valve of the air gun.

Abstract: A valve system utilizes a main valve body with a restricted diameter conduit communicating between a propulsion chamber and rear cavity and a smaller venting valve mechanically actuated to open the rear cavity to atmosphere, thereby causing the main valve body to open to pass pressurized air in the propulsion chamber to an orifice to power a projectile.

Abstract: A cocking and loading system for an air rifle utilizes a movable compression cylinder linked to the cocking arm to urge a piston into a cocked position, wherein the compression cylinder returns to a rest position urging a pellet feed tube through a magazine to load a pellet into the barrel.

Abstract: A linear magazine for an air gun advances upon actuation of a cocking mechanism. The magazine carries multiple projectiles for the air gun and translates perpendicularly to the bore (i.e., barrel) of the air gun to advance to the next projectile. The magazine places a series of projectiles in line with the bore of the gun while serving as a chamber for the projectile and gun and sealing to the air orifice and barrel bore of the air gun. In one embodiment, each hole or chamber of the linear magazine is arranged in a single row.

Abstract: A method of aligning a point of aim with a point of impact for a projectile device is disclosed. Using a superposition device coupled to the projectile device, at least three reference points are superposed within a first target area with at least three diverging beams of the superposition device. Positions for at least three of the reference points are noted. A projectile is shot from the projectile device at a second target area, while the positions of the at least three reference points are maintained, to create the point of impact. The point of aim for the projectile device is adjusted to correspond with the point of impact while the positions of the at least three reference points are maintained. A system for aligning a point of aim with a point of impact for a projectile device is also disclosed.

Using a superposition device coupled to the projectile device, at least one optical reference point is superposed within a first target area with at least one beam from the superposition device. A position of at least one of the optical reference points is noted. A projectile is expelled from the projectile device at a second target area, while the position of the at least one optical reference point is maintained, to create the point of impact. The point of aim for the projectile device is adjusted to align with the point of impact while the position of the at least one optical reference point is maintained.

Abstract: Methods and systems for aligning a point of aim with a point of impact for a projectile device are disclosed. Using a superposition device coupled to the projectile device, at least one optical reference point is superposed within a first target area. The point of impact is created on a second target area using a projectile expelled from the projectile device towards the second target area. The point of aim for the projectile device is aligned with the point of impact while the position of the at least one optical reference point is maintained. Parallax is eliminated (or minimized) by aligning a primary and a secondary sight alignment indicator with each other and with a common optical axis extending through a scope configured to be coupled with the projectile device.
