Quick answer

Choose the Turnover Quad SMG Large if you carry four large SMG magazines like Sig MPX or H&K MP7. Choose the Double 556 if you need a compact, two-mag rifle pouch that also fits in kangaroo pouches.

Capacity vs. compatibility: the core trade-off

The Turnover Quad SMG pouches hold up to four magazines, giving you more ammunition on your plate carrier without adding a bulky chest rig. The Double 556 holds two rifle magazines, which is lighter and leaves room for other gear on your cummerbund.

However, the Quad SMG pouches are designed specifically for SMG-sized magazines. The Double 556 uses elastic retention that fits a wider variety of items, including 5.56 magazines, tools, or even a radio. If you need a multi-purpose pouch, the Double 556 is more flexible.

Both attach via hook-and-loop Velcro, so they work with most plate carriers that have a Velcro cummerbund system. The Quad SMG pouches also integrate with the ADAPT Kangaroo Front Flap, while the Double 556 can be inserted into most kangaroo pouches.
