The US Palm CAT4 Storm is a compact 5.56 NATO AR pistol built around a cold-hammer-forged 11.50-inch barrel for superior barrel life and accuracy, featuring US Palm's Hurricane muzzle device — a helical flash hider and compensator hybrid that reduces both flash signature and muzzle rise. Fully ambidextrous controls include the safety selector, magazine release, and bolt catch, all operable from either side for maximum versatility with either hand. The reduced-angle pistol grip, flared magwell, and forward assist give the CAT4 a user-friendly ergonomic package straight from the factory, and 7075 T-6 aluminum receivers keep the build lightweight without sacrificing durability. A 30-round magazine is included, and the platform accepts all standard AR-15 accessories.
