Abstract: An ammunition magazine with an improved base locking, including: a hollow magazine body, a follower, a spring and a magazine base. The magazine body is equipped with track guides that correspond to grooves embodied on the magazine base, that the magazine base is guided onto. The spring is spirally embodied such that the first turn fully encompasses the surface of the magazine base and in the compressed state the rest of the spring, without the first turn, can fully fit into the follower pressed by the spring. The magazine base has a catch on one side and a hole positioned next to the catch. The magazine body has a slit allowing the catch to pass unobstructed into the magazine body and catch the detent spot on the spring positioned inside the magazine body. An advantage is improved safety of magazine base locking to the magazine body and simpler construction.

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.
