Abstract: A magazine limit block is provided having a base configured to fit within an interior of a magazine body and a tapered main body configured to guide and support a spring within an interior of a magazine body. The tapered main body extends upwardly from the base. A notch is formed at a top surface of the limit block and is configured to accommodate and provide space for a connection point of the spring and a follower. The main body is configured to occupy space within a magazine body to limit a number of rounds of ammunition that fit inside the magazine and guides the spring during cycling.
