    Abstract: A method and apparatus for intentionally slowing the speed at which detachable ammunition magazines can be interchanged in a firearm receiver. A magazine catch assembly includes a latch adapted to engage a recess of a standard magazine in the magazine well. A hand-activated crank interacts with threads of a push-rod portion of the latch so that manual rotation of the hand crank in one direction (e.g., counter-clockwise) displaces the latch after a sufficient number of turns. Reverse rotation of the hand crank returns the latch to its engaged condition ready to automatically re-engage the next magazine inserted into the firearm receiver. Alternatively, viscoelastic foam or other mechanical time-delay feature can be used instead of screw threads to introduce a mechanically transmitted dwell period before the latch is actuated.

  • Patent number: 8978282
    Abstract: A lever protects against inadvertent release of a magazine of a firearm if its ambidextrous release is hit by equipment when the firearm is carried. The lever is made from a projection, above the pivot point, having two opposing angles forward of the depression surface. The projection impacts the equipment before the depression surface is impacted (straight-on impact), which protects the assembly from inadvertent release of the magazine. An impact to the rear angle of the projection (a rear impact) increases the engagement of the lever with the magazine. An impact along the forward angle (from the front or straight-on) of the projection also serves to increase engagement of the lever with the magazine. The lever, with its projection having opposing angles, is specifically designed to protect the lever of an ambidextrous magazine catch from inadvertent release by impact/snag in the field.

    Abstract: A magazine lock for a firearm includes a magazine well and a magazine latch. The lock includes a tube nut positioned within a housing. The tube nut is connected to the magazine latch of the firearm. When tightened down, the tube nut prevents the magazine latch from releasing a magazine from the magazine well. A tool is provided to engage the tube nut and rotate the tube nut within the housing permitting the magazine latch to release the magazine. The housing includes a biased engagement feature that selectively prevents the rotation of the tube nut within the housing. The tool is configured to overcome the biased engagement feature and to engage the tube nut so that rotation of the tool rotates the tube nut. A breech block inserted into the top of a magazine inserted into the firearm may also be used to lock the firearm.

  • Patent number: 8733008
    Abstract: Example cartridge magazines for use within a curved handle of certain pistols have a laterally curved housing so that the pistols and magazines can fit comfortably along a user's body. Such curved pistols and magazines are particularly suited for carrying within a shirt or pants pocket. A curved pistol loaded with a curved magazine, for instance, can be carried comfortably in one pocket while an extra loaded magazine can be carried in another pocket. Example magazines carry single and multiple rows of cartridges along appropriately sized curved housings. The magazine's curvature provides a user with a prominent tactile feature that quickly indicates in which direction the magazine should be inserted within the pistol.

  • Publication number: 20140109451
    Abstract: The present invention involves techniques for rapid, flexible, partial and supplemental reloading of firearms using specialized actions, intermediate storage devices/feeds and multiple magazines, which may, in some embodiments, be simultaneously engaged with a firearm. The techniques disclosed include a feeding system, which may be a multiple-magazine feeding system, that allows a firearm to remain loaded and firing-ready with multiple loaded cartridges at all times, even during reloading operations. The invention also includes other techniques for flexible, non-wasteful, partially-empty reloading, to eliminate reloading paralysis, and allow the soldier or other user, not the size of a magazine, to determine when firing should continue and when and if it should pause.

  • Patent number: RE45986
    Abstract: A spring-loaded feed mechanism for a paintball loader. The feed mechanism includes an inner spool and an outer spool. A torsion spring is positioned between the inner and outer spools. The outer spool includes a pressure wall, from which the torsion spring is located on one end of the spring. A retaining wall is attached to the inner spool and is located at the opposite end of the torsion spring. When an operator of a paintball gun using the spring-loaded feed mechanism discontinues firing paintballs, the feed mechanism is stopped. Simultaneously, during the deceleration of the feed mechanism, the torsion spring is compressed, which allows the mechanical energy of the rotating feed mechanism to be stored within the compressed spring. When the operator desires to fire the paintball gun, the feed mechanism is accelerated to the requisite rotational speed. The compressed spring is release, thereby allowing the spring to assist in accelerating the feed mechanism to the necessary rotational speed.
