Abstract
A compact firearm spring arrangement within a firearm magazine utilizes two or more springs connected in a linear arrangement by a connecting cup that allows one spring to compress within the other, thereby resulting in a free length spring system having a reduced height when fully compressed while maintaining sufficient force for operation of the firearm. The reduced height of the spring when fully compressed allows for additional bullet storage space within a magazine of standard size or, alternatively, a more compact system within a magazine that provides an equal amount of bullet storage space while reducing the friction of operation of the firearm.
