    摘要: A rifle cartridge with a bullet has desirable penetration capabilities and controlled separation of components upon terminal impact. In embodiments of the invention, the bullet comprises a forward component, a lead core, and a copper jacket. The lead jacket having a leading edge portion that extends to the cylindrical mid portion. The forward component may have a forward pointed ogive portion, a cylindrical mid portion, a mid ogive portion, and a pair of cylindrical portions separated by an annular groove. The jacket having a cannelure at the annular groove and the casing upper lip crimped into the cannelure.

    摘要: In various embodiments, a projectile includes a projectile body including a tail portion, a nose portion, a barrel engaging portion between the nose portion and the tail portion, and a metal jacket that defines an exterior of the projectile that surrounds an interior solid core. In one or more embodiments the projectile includes one or more circumferential grooves defined in the interior core portion, each of the one or more circumferential grooves covered by and positioned adjacent to the metal jacket and within the barrel-engaging portion. In various embodiments, during firing of the projectile, the one or more circumferential grooves define a void that allows material of one or more of the metal jacket and interior solid core to displace into the void for reduction in radial stiffness to the projectile in the barrel engaging portion.

    摘要: A system for firing reduced energy cartridges from a modern sporting rifle utilizes a bolt assembly weighing less than a conventional bolt assembly for such rifles and utilizes blow back for cycling the bolt assembly rather than gas operation. A bolt insert in a polymer bolt carrier of the bolt assembly has a projection that fits within a recess on the rear face of reduced energy cartridges. The reduced energy cartridges having a polymer casing, a rimfire power load for propellant, the power load recessed from the rear face of the casing. Tuning the bolt may comprise adjusting the weight of the bolt or the sliding resistance of the bolt assembly in the upper receiver. The bolt may be formed by metal injection molding with a polymer bolt carrier attached thereto.

    摘要: An example charging handle comprises a body having a handle portion, a bolt engaging portion and a shaft portion extending forwardly from the handle portion to the bolt engaging portion. The handle portion of the body may have a starboard arm extending away from the shaft portion in a starboard direction and a port arm extending away from the shaft portion in a portward direction. The charging handle may comprise a grip member disposed about the handle portion of the body so that the grip member encapsulates the handle portion and the handle portion is disposed inside the grip member. The grip member may comprise a thermoplastic material overmolded on the handle portion of the body.
