Magpul Developed a 60-Round Quad Magazine

Quad Mag Prototype, 60-Round Capacity 2009

Shortly after the introduction of the original PMAG, Magpul began working on increased capacity solutions. The “Quad” or “Coffin” mag concept never delivered the reliability in rough handling and adverse conditions that they require from their magazine products, and so the design never made it into production. Lessons learned during this program eventually fed into the D-60 program.
