Description

    CROSS REFERENCE TO RELATED APPLICATIONS
  • This application claims priority from U.S. Utility patent application Ser. No. 15/703,793, filed Sep. 13, 2017, the contents of which are incorporated by reference.
  • STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT
  • This invention was not federally sponsored.
  • BACKGROUND OF THE INVENTION Field of the Invention
  • relates This application relates to semi-automatic firearms and more specifically the attachment of the ammunition feeding device.
  • BACKGROUND Prior Art
  • The present invention relates to systems and methods for efficiently releasing detachable magazines from firearms. Different types of firearms and firearm accessories have increased steadily over time in both functionality and flexibility, and today there is a wide variety of firearm modifications and/or accessories available. Innovation in the firearms industry is also driven by legislative trends, as firearm owners are required to respond by limiting the functionality of their firearms and/or accessories.
  • In recent times, Federal and/or State laws have limited features of semi-automatic firearms and/or also the capacity of firearm magazines. For example, in some jurisdictions, the use of detachable magazines with semi-automatic rifles is strictly regulated. Parts of the firearm common to someone in the art will only be given a brief description as necessary. A detachable magazine refers to an ammunition feeding device that can be removed from the firearm, reloaded and replaced. A common semi-automatic rifle is comprised of an upper and lower receiver.
  • These two parts together are commonly known as the action of the firearm. The lower receiver most commonly houses the magazine well and the fire control group. The fire control group is comprised of, at the very least, a trigger and a hammer. The upper receiver most commonly houses the bolt and the firing pin. The method of removing the magazine from the magazine well has been approached by different methods. With current laws and safety concerns, these methods fall short of a solution. Some current solutions to this problem require the use of a tool to remove the magazine, as in US patent 20130227869 to Alan T. Thordsen 2013 Sep. 5, but this does not address the issue of the action of the firearm needing to be taken down. The device in U.S. Pat. No. 8,756,845 to Courtney Harris 2014 Jun. 24 does address the issue of the action, but is done so using a difficult and cumbersome approach. The present embodiment solves the removal of the magazine in the safest and easiest fashion.
  • SUMMARY
  • In accordance to one embodiment, a catch holds a magazine in place until one wishes to remove it, only after opening the action of the firearm.
  • There has thus been outlined, rather broadly, the more important features of the invention in order that the detailed description thereof may be better understood, and in order that the present contribution to the art may be better appreciated.
