The Century Arms US Palm Storm CAT4 Rifle 5.56mm 30rd Magazine 16" Threaded Adjustable Stock Green is built as a duty-ready AR platform that delivers premium performance at an attainable price. Its Type III hardcoat anodized 7075-T6 aluminum upper and lower receivers provide a rigid, durable foundation, while the cold hammer forged 4150 chrome moly steel barrel and hybrid flash hider work together to enhance accuracy, reduce flash, and manage recoil. Fully ambidextrous controls and an innovative upper-to-handguard interface contribute to smooth handling and repeatable alignment for accessories and laser aiming systems.

This model is optic-ready with a full-length Picatinny rail, allowing shooters to configure their preferred sighting system for range work, training, or general-purpose use. The in-house designed US Palm grip and 7-sided M-LOK rail offer comfortable ergonomics and flexible mounting options, and the Magpul DT carbine stock provides an adjustable length of pull to fit a wide range of shooters. With its 30-round magazine capacity and Hiperfire EDT Designated Marksman Trigger, the Storm CAT4 is well suited for home protection, recreational shooting, and skill-building sessions, reflecting Century Arms’ focus on dependable design and thoughtful engineering.
