A mechanism for preventing a partially inserted magazine from accidently ejecting from the firearm. The improved firearms include any type of projectile weapon that employs a magazine to provide ammunition and include rifles and pistols. An improved magazine catch that includes both the primary latch and a safety latch. A method for engaging a magazine to a firearm for providing the firearm with ammunition without unintentionally dropping the magazine due to incomplete insertion.

Disclosed is a device for facilitating disassembly of a firearm and release of a magazine removably attached to the firearm. The device comprising a fulcrum configured to be attached to the firearm, wherein the firearm comprises an upper receiver, a lower receiver, a rear takedown pin and a magazine release mechanism, wherein the rear takedown pin is configured to secure the upper receiver to the lower receiver, wherein the magazine release mechanism is configured to release the magazine from the firearm based on actuation of the magazine release mechanism. Further, the device includes a lever arm configured to operationally engage with the fulcrum, wherein a first part of the lever arm is operationally engaged with the rear takedown pin, wherein a second part of the lever arm is operationally engaged with the magazine release mechanism, wherein actuation of the lever arm displaces the rear takedown pin and actuates the magazine release mechanism, wherein displacement of the rear takedown pin results in disassembly of the upper receiver from the lower receiver, wherein disassembly of the upper receiver from the lower receiver occurs prior to actuation of the magazine release mechanism.

A mount for a firearm has a body having a first clamp configured to engage a first edge of the rail, a jaw movably connected to the body and having a second clamp opposed to the first clamp and operable with the respective clamps to engage respective opposed lateral edges of the rail, a spring biasing the jaw toward the body, and at least a portion of the spring being between the clamps. There may be a pushrod connected to a first one of the body and the jaw and slidably received by the other of the body and the jaw. The spring may be laterally positioned to one side of the pushrod. The spring may be a coil spring having a spring axis offset from a pushrod axis defined by the pushrod.

Takedown pins for rifles have a pin movable in a direction along its length between an operating condition and a released condition. The pin has a first end portion that prevents relative movement of the upper receiver with respect to the lower receiver when the pin is in the operating condition. The first end portion has a lower end portion surface adapted to resist upward movement of the upper receiver's lug. The pin has an intermediate portion adjacent to the lower end portion surface defining a lower channel having a lower channel surface above the level of the lower end portion surface. When the pin is in the released condition, the lower channel is registered with the lug, and the lug is enabled to move upward with respect to the lower receiver by a limited distance to a disengaged position.

A firearm training system includes a device body simulating a firearm and a releasable magazine accessory. The magazine accessory is retained within a receptacle formed within a handle of the device body by a pair of catches and two springs that provide opposing forces on the magazine accessory. The firearm training system also includes an improved trigger assembly that reduces breakage of the trigger under repetitive trigger pulls.

A lower receiver for an AR15 type firearm is provided comprising a non-detachable magazine movable in the receiver between a first locked position where the firearm is ready for use (i.e. cocked and ready for firing) and a second non-operational position where the magazine is lowered sufficiently to open a window or aperture in the receiver enabling the user to load fresh shell cartridges into the magazine. A locking mechanism also is provided for controlling the position of the non-detachable magazine between the first and second positions. A child-proof lock further is provided to prevent undesired activation of the locking mechanism. Additionally, a novel locking plate disposed between the lower receiver's frame and the receiver's stock extension tube provides enhanced support for the extension tube and an accessory attachment point for a shoulder strap or sling.

A rifle has a receiver. The receiver has a recess with a rectilinear major section and a trapezoidal minor section. The minor section extends upwardly from the major section. The receiver has a chamber above the recess. A rectilinear container has a lid with an upwardly extending projection. The lid is removably received in the minor section of the recess. A plurality of bullets are removably positioned in the container. The bullets extend upwardly through a passageway in the lid and into the chamber.

A device implementable on a firearm includes a magazine release having a magazine catch and a magazine release button coupled to the magazine catch. When the magazine release is installed on the firearm, the magazine catch is configured to hold a magazine in a magazine well of the firearm when the magazine release button is not pressed and the magazine catch is configured to release the magazine from the magazine well when the magazine release button is pressed. The magazine release button includes a coupler configured to couple the magazine release button to the magazine catch. The magazine release button also includes a detachable pedal slidingly attachable to the coupler.
