US PALM is an American firearms-accessory brand best known for AK magazines and related rifle gear. The name has also appeared on complete firearms tied to modern defensive rifle configurations. In this catalog, US PALM is represented by CAT4 Storm AR-style rifles chambered in 5.56 NATO. The stocked models include compact 11.5-inch and 16-inch configurations with black finishes, so the focus here is squarely on AR-pattern 5.56 rifles rather than the brand's accessory catalog.
