摘要： A barrel for a semiautomatic firearm operating under the short recoil system has one or more cam followers projecting outwardly to engage one or more cams positioned on an inner surface of a slide surrounding the barrel. Interaction between the cams and the cam followers controls the angle between the longitudinal axis of the barrel and the axis of motion of the slide to prevent the breech end of the barrel from moving too far as the barrel tilts as it unlocks from the slide, ensuring that the extractor will engage the rim of a spent casing and extract it from the chamber during recoil.

摘要： A weapon system having a breechblock, wherein the breechblock can be mechanically connected to a drive of the weapon system. The weapon system comprises means which are designed in such a way that a mechanical separation occurs between the breechblock and the breechblock drive with the recoil of the recoiling masses of the weapon system. With the forward motion of the recoiling masses, the mechanical connection between the breechblock drive and the breechblock is re-formed.

摘要： A firearm using blowback action has a barrel which is movably mounted within a shroud which is fixedly mounted on the firearm's frame. A gas space is formed between the barrel and the shroud by a difference between the inner diameter of the shroud and the outer diameter of the barrel. At least one gas port provides fluid communication between the bore of the barrel and the gas space. During firing of a cartridge, pressurized gas in the gas space applies a force to the barrel which moves relatively to the shroud away from the muzzle end of the firearm to engage a slide or bolt, helping to move it out of battery and extract the spent cartridge casing. Gas is vented to the atmosphere through a gas vent defined between the barrel and the shroud in fluid communication with the gas space.

摘要： A light-weight, shoulder-firable, armor-penetrating gun characterized by a recoiling barrel confined to coaxial movement by a pair of longitudinally spaced bushings within the gun housing, the recoiling barrel being adapted to carry rearward the elongated bolt carrier containing the bolt for compressing the recoil spring, and a stop mechanism associated with the barrel and the housing for limiting the rearward travel of the barrel for early disengagement between the barrel and the bolt carrier, and a barrel spring in the front of the housing for returning the barrel to its normal battery position.

摘要： A barrier comprising a base unit composed of a bullet resistant material and a transparent upper wall removably interconnected to the base unit and composed of a bullet resistant material. The base unit includes a front wall and two side walls extending from the front wall to provide protection to the front and sides of a person standing behind the barrier. A series of casters, preferably locking casters, are attached to the bottom edges of the side walls, and a pair of handles connected to each of the side walls permitting the barrier to be conveniently transported from one site to another.
