US Palm Cat4 Rifle 5.56 NATO 30rd Magazine 16" Barrel Black

The STORM CAT4 is a duty-ready rifle built to exceed expectations—delivering premium $2000+ rifle performance at an attainable $1300 price point. Designed by experts who live and breathe the AR platform the STORM CAT4 was built for shooters who demand more without overpaying for a name.

Every critical wear point has been reinforced with hardened user-serviceable components to ensure long-term durability and reliability under hard use. Fully ambidextrous controls provide seamless operation in any environment while an innovative upper-to-handguard interface enhances rigidity—maximizing mechanical accuracy and ensuring repeatability for laser aiming systems.

Ergonomics are dialed in with a complete in-house designed grip engineered with user inputs to maximize control and comfort. A hybrid flash hider reduces both flash signature and felt recoil keeping you on target when it matters most. Built without compromise. Engineered with purpose. When conditions are at their worst the CAT4 stands ready—because when you step into the storm your rifle shouldn’t have weak points.

HURRICANE Hybrid Flash Hider/Compensator

The US PALM Hurricane Hybrid Muzzle Device on the Storm CAT 4 is one of the rifle’s standout design elements because it’s built to do two jobs at once: flash suppression and recoil control. Instead of being just a standard birdcage flash hider or a straight compensator it’s a hybrid comp/flash hider with a very aggressive helical twisted-prong design that follows the barrel’s twist direction. That spiral geometry isn’t just for looks—it helps redirect gases in a way that keeps the rifle flatter during fast follow-up shots while still helping break up muzzle flash.

Full Ambidextrous Controls

The US PALM Storm CAT 4’s full ambidextrous controls are engineered for shooters who demand speed adaptability and total command from either side of the rifle. Every critical touchpoint—from the safety selector and magazine release to the bolt catch/release and charging handle—is fully accessible without forcing the shooter to break grip or shift position. This creates a faster more intuitive shooting experience whether you’re running support-side transitions working barricades or performing rapid reloads under pressure.

MONO-LOC HANDGUARD SYSTEM

Built for absolute confidence the US PALM Mono-Loc handguard system delivers a monolithic-level lockup that pushes rigidity and control beyond the limits of a standard free-float rail. Its precision rear-locking interface keys directly into the upper receiver creating an ultra-secure foundation that resists flex maintains accessory alignment and keeps lasers or optics locked on target under hard use.

With a continuous top rail full M-LOK modularity and a rigid seven-sided profile the Mono-Loc gives shooters maximum space for mission-critical accessories without sacrificing balance or speed. Whether driving through barricades loading into sling tension or running high-tempo drills the system stays rock solid and repeatable.

This is more than a handguard—it’s a stability platform engineered for aggressive movement zero retention and total front-end control.
