BACKGROUND OF THE INVENTION1. Field of Invention
This invention relates to firearms and more particularly to devices for ejecting magazine cartridges from 22 caliber rifles.
2. Description of Related Art
The present invention relates generally to a .22 semi-automatic rifle magazine release. Particularly, the present invention relates to a device that when integrated into a Ruger 10/22 semi-automatic rifle, it allows for a quick ejection of the magazine.
The .22 semi-automatic rifle is very popular for target practice and for small-game hunting. One of the most common complaints about the .22 semi-automatic rifle is regarding the removal of the magazine to reload the weapon. Removing the magazine is often difficult and time consuming.
In order to reload the weapon, the magazine must be removed. With the conventional magazine release, the user must push the magazine latch with one hand and then wiggle the magazine with the other hand to remove it. This process is inconvenient and takes unnecessary time. For competition shooting it is necessary for the competitor to reload as fast as possible.
Often the user of a .22 semi-automatic rifle wears gloves when using the weapon. With the conventional magazine release it is difficult to grasp the magazine and wiggle it out. The user often needs to set the weapon down and remove his gloves prior to removing the magazine, and then put his gloves back on prior to using the weapon again. This causes inconvenience to the user who wants to continue shooting.
Therefore, there remains a need for a faster, quicker, and effective magazine release for the .22 semi-automatic rifle.
SUMMARY OF THE INVENTIONIt is an object of the present invention to overcome the drawbacks and shortcomings of the conventional magazine release of the .22 semi-automatic rifle.

While in the engaged state, as shown in
A spring 26 is disposed between an upper portion of the ejector lever 20 and an internal wall 30 of the housing. The spring 26 is biased to provided a force against the upper portion of the lever 20 to keep it from inadvertently disengaging the stud or tab 44 of the magazine 40. When the operator of the rifle desires to eject the magazine, the lever 20 is activated by moving the free end 22 of the lever 20 in the direction of arrow 2, as shown in
The disengaged state is achieved once the lever 20 rotates enough so that the end 24 is no longer disposed beneath the stud 94 of the magazine 90. At that moment, the device 100 of the present invention will still be applying a downward force upon the magazine (in the direction of arrows 3 and 4) and the magazine will be automatically ejected without the user having to pull or wiggle the magazine free from the firearm.
The actuator 110 translates downward when in operation and going between the engaged and disengaged states. The actuator translates upwards when in operation and going from the disengaged to the engaged state. The alignment slot 140 is operably configured to receive pin 15. As the actuator translates up and down, the pin 15 within the alignment slot 140 assists with keeping the actuator within the correct position within the housing during operation. The pin 15 stops the upward movement of the actuator when the pin engages the bottom of the slot 140. The trigger housing 1, includes an internal wall 30.
