US PALM CAT4 Series

The CAT4 is part of US PALM’s line of modern AR pistols. Built with quality components and designed for real-world use, the CAT4 combines the proven AR platform with a compact pistol configuration. US PALM has earned a strong reputation for producing durable and reliable firearms, and the CAT4 continues that tradition with a focus on performance and user-friendly features.

5.56 NATO Performance

Chambered in 5.56 NATO, the CAT4 provides excellent ballistic performance and widespread ammunition availability. This caliber offers a flat trajectory, manageable recoil, and effective terminal ballistics at typical defensive and training distances. The pistol configuration allows shooters to enjoy the benefits of the 5.56 NATO cartridge in a much more compact and maneuverable platform than a traditional rifle.

30-Round Magazine Capacity

The CAT4 comes with a 30-round magazine, providing substantial firepower for defensive, training, or recreational use. The standard AR-15 magazine compatibility allows users to take advantage of the wide variety of high-quality magazines available on the market. This capacity makes the pistol well-suited for situations where multiple follow-up shots may be necessary.

Compact and Maneuverable Design

As a pistol configuration, the US PALM CAT4 offers significantly better handling in tight spaces compared to a full-length rifle. Its shorter overall length makes it ideal for home defense, vehicle carry, and use in confined environments. The black finish provides a low-visibility, professional appearance while maintaining durability and resistance to wear.
