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. ## Claims ### Claim 1 A firearm apparatus, comprising: (a) a firearm upper assembly and a firearm lower assembly, (b) the firearm lower assembly comprising a firearm magazine container, wherein swapping of or refilling of a firearm magazine resident within the firearm magazine container necessitates at least partial removal of the firearm upper assembly from the firearm lower assembly and further, requires removal of a 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. ### Claim 2 (depends on 1) The firearm apparatus according to claim 1 wherein the firearm magazine container has a closed inaccessible bottom end and an opening in the top end for receiving a firearm magazine. ### Claim 3 (depends on 1) The firearm apparatus according to claim 1 wherein refilling of or swapping of a firearm magazine present within the magazine container necessitates complete removal of the firearm upper assembly from the firearm lower assembly. ### Claim 4 (depends on 1) The firearm apparatus according to claim 1 wherein the firearm lower assemble or the firearm magazine container is made from a resilient material that is not easily removed from the firearm lower assembly. ### Claim 5 (depends on 4) The firearm apparatus according to claim 4 wherein the resilient material is a metal. ### Claim 6 (depends on 4) The firearm apparatus according to claim 4 wherein the resilient material is a polymer. ### Claim 7 (depends on 4) The firearm apparatus according to claim 4 wherein the resilient material comprises a mixture of a metal and a polymer. ### Claim 8 (depends on 1) The firearm apparatus according to claim 1 wherein the firearm magazine has a maximum capacity of 100 rounds. ### Claim 9 (depends on 1) The firearm apparatus according to claim 1 wherein the firearm magazine has a maximum capacity of 30 rounds. ### Claim 10 (depends on 1) The firearm apparatus according to claim 1 wherein the firearm magazine has a maximum capacity of 20 rounds. ### Claim 11 (depends on 1) The firearm apparatus according to claim 1 wherein the firearm magazine has a maximum capacity of 10 rounds. ### Claim 12 (depends on 1) The firearm apparatus according to claim 1 wherein the firearm magazine has a maximum capacity of 5 rounds. ### Claim 13 (depends on 1) The firearm apparatus according to claim 1 wherein the firearm apparatus is a semi-automatic rifle. ### Claim 14 (depends on 9) The firearm apparatus according to claim 9 wherein the firearm apparatus is an AR-15 or AR-16 semi-automatic rifle. ### Claim 15 (depends on 9) The firearm apparatus according to claim 9 wherein the firearm apparatus is a semi-automatic pistol. ### Claim 16 (depends on 1) The firearm apparatus according to claim 1 wherein the firearm magazine container and the firearm magazine are combined into a refillable only single firearm container-firearm magazine device. ### Claim 17 (depends on 1) The firearm device according to claim 1 wherein the retaining device is retaining screw or retaining pin. ### Claim 18 (depends on 1) The firearm device according to claim 1 wherein an indicator is present in the firearm lower assembly or in the firearm upper assembly to show or indicate how many rounds of ammunition is present within the firearm magazine. ### Claim 19 A method of converting an existing firearm that has a readily detachable firearm magazine into a firearm that has a non-detachable firearm magazine, comprising: removing an existing active magazine position button; replacing the active magazine position button with a dummy or non-active magazine position button. ### Claim 20 A kit for the conversion of a firearm with a readily detachable firearm magazine into a firearm with a non-readily detachable firearm magazine′ comprising: a retaining device; a drill guide template; a modified magazine lock, wherein the shaft or spindle of the magazine lock has a flattened-out portion to facilitate engagement with the retaining device; a modified magazine position button, wherein the modified magazine button has an optionally threaded hole configured to allow the retaining device to pass through.
