  • Patent number: 5561563
    Abstract: A lens apparatus is disclosed for use with a firearm scope. The lens apparatus includes first and second polarized lenses that move relative to each other. When differently colored lens materials are used and when moved relative to each other, the color seen through the two polarized lenses changes. In affixing the first and second polarized lenses to the firearm scope, first and second connection assemblies are utilized. The two connection assemblies have first and second latch release members, respectively. The two latch release members are located on the right and left sides of a scope when a user is in the normal shooting position. Upon actuation of the latch release member, pivotal movement of the polarized lenses, relative to the firearm scope lenses occurs. Each of the two connection assemblies includes a sleeve member and a cap lid. The sleeve member is flexible to surround portions of the firearm scope and is made of a material different from the cap lid material.

  • Patent number: 5526600
    Abstract: An extended capacity cartridge magazine assembly for containing and feeding cartridges to a firearm is disclosed. The magazine includes a metal body for containing cartridges having an upper outlet through which cartridges may exit the magazine into the firing chamber of the firearm and a base plate for covering the bottom of the magazine body. A follower body is disposed within the body of the magazine for biasing cartridges toward the upper outlet. The follower body and the magazine body have certain dimensions to prevent an unwanted amount of rotation of the follower body when 0.45 caliber cartridges are being used. A collar slidably movable along the length of the magazine body is adapted to retain the base plate in a fixed position with respect to the magazine body. A flexible bumper plate interconnects with the bottom surface of the collar to secure the cartridge magazine assembly.

  • Patent number: 5507110
    Abstract: A restricted capacity cartridge magazine includes a magazine body having four walls defining a chamber for housing cartridges, a bottom end and an open end through which cartridges may exit and a follower assembly for moving cartridges through the chamber toward the open end. The follower assembly includes a follower body and a constant force spring unit. Blocking members formed in opposing side walls terminate at a slot forming opposing lips which extend a predetermined distance into the chamber to contact portions of the the lowermost cartridges in the magazine to limit the movement of cartridges away from the open end of the magazine. The constant force spring unit terminates at a length such that the magazine is disabled if the follower body is moved past a predetermined distance from the open end of the magazine.

  • Patent number: 5375359
    Abstract: A cartridge magazine for containing and feeding .22 rimfire cartridges including truncated, hollow point or flat nosed cartridges is disclosed. The magazine includes a metal magazine body having first and second sidewalls and first and second end walls. The cartridge storage area is defined by these four walls. The magazine body has a cross-sectional area that is substantially the same throughout the height of the magazine body. The dimensions related to the cross-sectional area are critical to proper feeding of truncated cartridges into the firearm while avoiding cartridge jamming. The magazine body includes an outlet section from which the cartridges enter the firearm from the magazine body. A number of structural members are located at the outlet section to assist in proper feeding of the cartridges.

  • Patent number: 5357703
    Abstract: A magazine is disclosed for use with a pistol having a plastic firearm latch that is used to hold the magazine in the pistol well. The magazine includes an all metal magazine body. A non-metal magazine latch member is connected to the magazine body. When the magazine is held in the pistol well, the plastic firearm latch in the pistol engages the non-metal magazine latch member. In one embodiment, a carbon fiber filled firearm latch is substituted for the plastic firearm latch. A spacer assembly is held adjacent an end wall of the magazine body. The spacer assembly has a smooth outer surface for engagement by rim ends of cartridges during their movement relative to the magazine body. A non-symmetrical rib formed on the inner surface of a side wall of the magazine body is engagable by cartridges during their movement to prevent a premature bolt hold open condition.
