Abstract: The present invention relates to a method and a device by means of which it has been made possible, without gas discharge to the surrounding environment, to accelerate the speed of a powder-gas-driven projectile from zero to a speed which gives the projectile free-flying characteristics. According to the invention, this has been made possible by utilizing at least some of the expansion force from the propellant powder charge, which discharges gas when it is initiated, for, by a displaceable piston, driving a countermass out of the rear part of the projectile in the direction opposite to the desired flying direction of the projectile.

The net containing tube receives a high strength net body and a propellant board with a gas receiving concave shaped surface inside. Multiple bullets received in the shot holes are coupled to a periphery of the net body. The bottom of the net contained tube has multiple gas holes and an air outlet board.

Abstract: Especially in hunting, the choice of bullets has to be such that it is in keeping with the wild animals to be hunted. According to the desired effect on the target, deformation bullets or partial fragmentation bullets are used. Since both types of bullets are different, the position of the point of impact from the same weapon is different. According to the type of bullet used, the weapon must be oriented differently in relation to the target. This can be obstructive and if insufficient attention is paid, can result in misses.

The module housing includes at least one pin receiver defined by two openings formed in the module housing, one on each lateral side of the housing. A module pin is received in the pin receiver and at least one trigger group component is mounted or supported for rotation on the module pin. The pin receiver is located on the module housing so as to align with a pin receptacle of the firearm when the module housing is in the operating position. By locating the pin receiver in the module housing so as to align with a corresponding pin receptacle of the firearm when the module housing is in the operating position, the trigger group module and the trigger group components housed in the module housing may be readily supported by the OEM pin receptacle.

Abstract: An arrestor drives a valve-body. An air source supplies air into the valve-body to control a strike-controlling unit and bolt to reciprocally move. The valve-body has linking and arresting sections. The arresting section communicates with the linking section via a ventiduct. The arresting section is formed with a passage. An inner wall of the passage has a sloped annular groove. The annular groove communicates with the air source via an intake. A shaft and resilient member are accommodated in the passage. The shaft is reciprocally drivable by the arrestor and resilient member. Via a relief duct, the ventiduct communicates with a part of the passage where the resilient member is accommodated. The arresting section is formed with an escape hole via which the passage communicates with the outer side. The shaft is formed with a first annular groove corresponding to the annular groove of the passage.

Abstract: A pneumatic sonobuoy launcher adapted for simultaneously storing, and sequentially and independently launching, at least two sonobuoys includes a barrel with a closed back end, an expulsion end opposite the back end and an interior sonobuoy-guiding channel extending between the opposed ends. The channel is adapted for storing a series of sonobuoys including rearwardmost and forwardmost sonobuoys stored, respectively, closest to the back end of the barrel and closest to the expulsion end of the barrel. Each stored sonobuoy occupies a distinct region of the channel separated by an interval from at least one other region.

Abstract: A riflescope includes an objective optic assembly with a bottom surface that defines a scoop. Upon mounting the riflescope, the scoop receives a portion of a firearm. The scoop eliminates interference between the objective optic assembly and the firearm and allows a centerline of the riflescope to be placed in closer proximity to a centerline of the firearm.

Abstract: A removable air bleed assembly for use with between a paintball gun and an auxiliary system includes a pin having an elongated pin channel extending through a majority of the pin to bleed pressurized air from the paintball gun. An air conduit is coupled between and in fluid communication with the removable pin and an auxiliary assembly to facilitate passage of the pressurized air from the paintball gun to the auxiliary assembly. The removable pin can be manually removed from the paintball gun without the need for any tools. The auxiliary system can be at least one of an agitator system and an uploader system, as an example.

Abstract: An actuating mechanism used in an air gun is disclosed to include a hammer, a hook member hooked on the hammer for moving the hammer to the striking position, and a movable block supported on said spring member below a slide of the air gun.

Abstract: An aiming sight includes a controller, a power supply, an LED array, and a collimator. The power supply powers the LEDs to turn-on and turn-off, and powers the collimator to rotate. The collimator rotates to different rotational positions while the controller, the power supply, and the LED array remain fixed in place. The LEDs are positioned such that one LED and the collimator are at a constant angle and separated by a constant focal distance for each collimator position. The controller controls the collimator to rotate to a collimator position to generate an aiming dot at an angular position corresponding to the collimator position. The controller turns-on the LED which is at the constant angle and separated from the collimator by the constant focal distance and turns-off the remaining LEDs such that the collimator collimates light from the turned-on LED into the aiming dot at the angular position corresponding to the collimator position.
