Abstract

A device for converting a firearm to a fixed magazine is disclosed. The device includes a one-way internally threaded bolt comprising of an internally threaded section and a one-way head. The internally threaded section is able to engage with the externally threaded portion of the magazine catch and the head is configured so that a screw driver is only able to rotate the one-way internally threaded bolt in a tightening direction. A method for loading a firearm having a fixed magazine is also disclosed.

1 . An apparatus comprising: a one-way internally threaded bolt comprising an internally threaded section and a one-way head, hereafter referred to as the Spartan Lock, wherein the internally threaded section is able to engage with the externally threaded portion of the magazine catch, and the head is configured so that a screw driver is only able to rotate the Spartan Lock in a tightening direction. 
     
     
         2 . The apparatus of  claim 1 , wherein the Spartan Lock comprises a material that is selected from the group consisting of metal, ceramics, plastics, wood, alloys, and combinations thereof. 
     
     
         3 . The apparatus of  claim 1 , further comprising a spacer comprising a piece that corresponds to the Spartan Lock. 
     
     
         4 . The apparatus of  claim 1 , wherein the Spartan Lock, the spacer, and the magazine catch member are separate. 
     
     
         5 . The apparatus of  claim 1 , further comprising a firearm; wherein the firearm comprises a receiver; the Spartan Lock extends into the receiver and is engaged with the magazine catch and spacer; and the magazine catch and spacer abuts the receiver. 
     
     
         6 . A method comprising: installing the Spartan Lock; and securing the Spartan Lock to a magazine catch and spacer, such that the magazine catch engages a magazine and the magazine cannot be removed from a receiver. 
     
     
         7 . The method of  claim 6 , further comprising inserting the magazine into the receiver. 
     
     
         8 . The method of  claim 6 , further comprising: moving a takedown pin to a degree to allow an upper receiver to rotate about a pivot pin; rotating the upper to expose an entrance of the magazine; and placing ammunition in the magazine. 
     
     
         9 . The method of  claim 8 , further comprising returning the upper to a closed position; and securing the upper to the receiver with the takedown pin.
