Elite Tactical Systems is a manufacture that builds tough magazines with advanced polymers that provide extreme impact so they won't break if dropped. They also have temperature tolerances so that the magazines won't get brittle over time. The durable construction of Elite Tactical Systems' mags eliminates creep, so your feed lips and body won't spread when stored even fully loaded. The innovative slim design can be coupled and uncoupled in a matter of seconds without the need for tools. They have also designed mags that are integrated for easy grab and pull with no external pieces, allowing you to couple together two or more at a time. Maintenance is easy with Elite Tactical Systems.
