1. A variable capacity modular firearm magazine, comprising: a butt plate having a front wall, a pair of opposing side walls, and a spring retention cavity disposed along a bottom wall;one or more rigid modular bodies, each including an elongated hollow tubular shape having a front side wall, a back side wall and a pair of opposing side walls defining an open top end and an open bottom end, each of said one or more rigid modular bodies further includinga pair of flanges extending outward along a bottom end of each of the opposing side walls, said flanges being separated by a first distance, and further including an elongated channel that is disposed along an upper end of each of the front wall and the opposing side walls, said channel including a pair of nubs that are disposed within the channels at a complementary location to the first distance,wherein each of the flanges and channels include a complementary shape and dimension;a receiver member that includes a rigid elongated hollow tubular shape having a front side wall, a back side wall and a pair of opposing side walls defining an open top end and an open bottom end; anda cartridge engagement unit that includes at least one spring and a follower, said unit having a size and shape that are configured to operate within each of the receiver member and the one or more modular bodies,wherein each of the butt plate and the receiver member further include at least one fastener. 2. The device of claim 1, wherein the cartridge engagement unit further includes a plurality of springs and at least one spring connector that is configured to align and stack two of the plurality of springs, each of said spring connectors including a generally planar middle portion that is in communication with an upper spring retention member and a lower spring retention member. 3. The device of claim 2, wherein each of the spring retention members include at least one of a protrusion and a generally hollow box-like structure. 4. The device of claim 2, wherein each of the plurality of springs include an identical length. 5. The device of claim 2, wherein at least one of the plurality of springs include a length that is different than a length of another of the plurality of springs. 6. The device of claim 1, further comprising: a plurality of rigid modular bodies, each of said bodies including an identical length. 7. The device of claim 1, further comprising: a plurality of rigid modular bodies, wherein at least one of the plurality of bodies includes a length that is different than a length of another of the plurality of bodies. 8. The device of claim 1, wherein the receiver member includes a shape that is complementary to a shape of a firearm magwell and is configured to be removably secured therein. 9. The device of claim 8, wherein the receiver member further includes at least one coupler that is configured to removably engage a mag-catch of the firearm. 10. The device of claim 1, wherein the butt plate fasteners include a pair of longitudinally extending grooves that are disposed along the side walls of the butt plate. 11. The device of claim 1, wherein the fasteners of the receiver member comprises: a pair of flanges extending outward along a bottom end of each of the opposing side walls, said flanges being separated by the first distance. 12. The device of claim 1, wherein the butt plate is in communication with the bottom end of one of the rigid modular bodies; the receiver member is in communication with the top end of the same rigid modular body; andthe cartridge engagement unit is positioned within each of the receiver member and the one rigid modular body so that the at least one spring is in contact with the protrusion of the butt plate. 13. The device of claim 1, wherein each of the one or more rigid bodies and the receiver member includes a dimension suitable for receiving and storing a firearm cartridge. 14. The device of claim 1, wherein each of the one or more rigid bodies further includes an expansion gap that is disposed along the back wall at a location adjacent to a top surface thereof. 15. The device of claim 14, wherein each of the expansion gaps consists of: an elongated narrow slit that extends from the top surface towards the bottom surface, said narrow slit terminating into an open section,wherein the expansion gap of each of the one or more rigid bodies functions to allow a width of the upper portion of a first rigid body to expand and contract the channels located thereon, in order to receive the flanges of a second rigid body.
