Part of the Century Arms family, US Palm is known for making magazines, grips and other accessories for AK-platform firearms. This year, the company is branching out to offer suppressors and complete firearms, including its new STORM CAT4 series of rifles and pistols.
US Palm calls the CAT4 “a duty-ready rifle built to exceed expectations—delivering premium, $2,000+ rifle performance at an attainable $1,300 price point.” At their core, CAT4 firearms are based on the direct gas impingement AR-15 design. Upper and lower receivers are made of billet 7075-T6 aluminum and given a Type III hardcoat anodized finish.
The upper receiver has a user-serviceable hardened steel case deflector/forward assist housing, while the lower has an integrated trigger guard and flared magazine well. Controls are bilateral for fully ambidextrous use, and the safety selector has a 45-degree throw. The fire control components are Hiperfire’s single-stage EDT Designated Marksman trigger.
Chambered for 5.56 NATO, barrels are cold-hammer-forged from 4150 chrome moly steel and have 1:7-inch twist rate rifling and a nitride finish. Both the bolt and barrel extension are given a DLC coating. The aluminum handguard uses US Palm’s Mono-Loc system, attaching to the receiver to allow the barrel to free float. It has both M-Lok accessory slots and a full-length top Picatinny rail.
Known for its firearms accessories, US Palm adds its own unique touch to CAT4 firearms. The Reduced Angle pistol grip was engineered in-house, as was the Hurricane Hybrid Flash Hider, which is designed for both flash suppression and recoil control.
The STORM CAT4 is available in both rifle and pistol versions. The rifle version uses a 16-inch barrel, a Magpul DT telescoping stock and weighs 7 pounds. The pistol version has an 11.5-inch barrel, a Magpul BTR telescoping stabilizing arm brace and weighs 6 pounds. Both rifles and pistols are available with either an all-black or Storm Green finish and have an MSRP of $1,399. For more information, see the company’s website.
