US Palm Storm CAT 4 Rifle – Precision 5.56mm Carbine

The US Palm Storm CAT 4 rifle represents a deliberate balance of weight savings and battlefield-proven ergonomics. Chambered in 5.56mm NATO, this carbine is engineered for shooters who demand a reliable platform without unnecessary bulk. Every component, from the free-floated handguard to the adjustable stock, is designed for consistent performance under routine use. Whether you are building a primary defensive carbine or upgrading your range setup, the US Palm Storm CAT 4 rifle delivers a confident shooting experience.

Overview

The US Palm Storm CAT 4 is a direct-impingement rifle built on a forged 7075-T6 aluminum receiver. It features a 16-inch chrome-lined barrel with a 1:7 twist rate, optimized for stabilizing 55- to 77-grain 5.56mm ammunition. The rifle incorporates US Palm’s proprietary bolt carrier group with a enhanced extractor and chrome-plated firing pin for reliable ignition. The handguard is a slim, M-Lok compatible design that reduces overall weight while maintaining rigidity for accessory mounting. This model is a purpose-built carbine for shooters who prioritize function over flash.

Features & Specs

  • Receiver and Barrel: Forged 7075-T6 aluminum upper and lower receivers. 16-inch chrome-lined 4150 steel barrel with a 1:7 twist, M4 feed ramps, and a standard A2 flash hider.
  • Operating System: Direct impingement with a US Palm enhanced bolt carrier group. Includes a chrome-plated firing pin, dual ejector springs, and a high-pressure tested bolt.
  • Handguard and Furniture: US Palm Storm free-float M-Lok handguard (12.5-inch) with integrated heat shield. Adjustable 6-position buttstock with a rubber buttpad and a US Palm pistol grip with storage compartment.
  • Sights and Optics: Flip-up rear sight and front sight post included. Flat-top upper with a Picatinny rail for optic mounting.
  • Caliber: 5.56mm NATO (also accepts .223 Remington).
  • Weight: 6.8 pounds (unloaded). Overall length: 32-35 inches (stock collapsed to extended).
  • Capacity: Accepts all standard AR-15 pattern magazines. Ships with one US Palm 30-round magazine.

Who It Is For

The US Palm Storm CAT 4 rifle is designed for the practical shooter who needs a reliable 5.56mm carbine for home defense, range training, or patrol use. It suits the enthusiast who values a lightweight build without sacrificing accuracy or durability. The adjustable stock and slim handguard make it manageable for shooters of varying sizes, while the chrome-lined barrel ensures longevity for high-volume shooters. If you require a no-frills, field-ready platform that performs consistently with standard ammunition, this rifle is a direct fit. It is not a competition race gun or a precision benchrest rifle; it is a working carbine built for real-world handling.

  • Home defense and personal protection applications
  • Range training and skill development
  • Patrol and duty use (compatible with standard accessories)
