The Hurricane Hybrid muzzle device uses a helical, twisted-prong design that follows the barrel's twist direction, combining flash suppression with recoil mitigation to help reduce muzzle rise while dispersing flash. The Mono-Loc handguard system uses a precision rear-locking interface that integrates securely with the upper receiver, maintaining alignment for optics and accessories under demanding use. Fully ambidextrous controls give shooters intuitive access to the safety selector, magazine release, bolt catch, and charging handle without changing grip, supporting faster manipulation in dynamic shooting environments. The Hiperfire EDT Designated Marksman trigger delivers a refined pull suited to precision work.

US Palm designs AR-platform rifles and magazine components focused on ergonomics and rapid manipulation under stress, building the Storm CAT4 around the same principles that shaped their original PALM magazine grip design.
