Century Arms US Palm STORM CAT4 5.56 NATO 11.5" 30-Round AR Pistol

The Century Arms STORM CAT4 is a semi-automatic AR-15 pistol chambered for 5.56x45mm NATO and .223 Remington, built for shooters who want a compact, maneuverable platform. It ships with a 30-round magazine and has no iron sights, making it optics-ready for mounting a red dot or similar sight.

The receiver has a matte black anodized finish, the handguard is Mono-Loc M-LOK, and the pistol weighs about 6 pounds with an overall length of 29 to 32.3 inches depending on brace position.

Controls are fully ambidextrous, including the safety. The trigger is a Hiperfire EDT designated marksman unit, the grip is a US Palm reduced-angle model, and the stock is a Magpul BTR arm brace.
