Abstract:
A firearm apparatus is described comprising a firearm upper assembly and a firearm lower assembly, the firearm lower assembly comprising a firearm magazine container, wherein swapping of or refilling of a firearm magazine that is resident within the magazine container necessitates at least partial removal of the firearm upper assembly or may require complete removal of the firearm upper assembly from the firearm lower assembly. Further, such an apparatus requires removal of a firearm magazine retaining device that secures a firearm magazine lock wherein the retaining device is inaccessible without the at least partial removal of the firearm upper assembly from the firearm lower assembly. The firearm lower assembly may have a firearm magazine container that has a closed or partially closed bottom end to prevent switching out of a firearm magazine and the firearm lower assembly may have an opening in the top end sized for receiving a firearm magazine. A new firearm lower assembly is described that has no magazine position button as well as a conversion kit and a method of using a conversion kit to convert a semi-automatic firearm with a readily detachable firearm magazine into a firearm having a non-readily detachable firearm magazine.
