Product DescriptionThe Phase 5 Weapon Systems FATman Hex Brake is a precision muzzle brake engineered for AR-platform rifles chambered in .223 Remington and 5.56x45mm NATO. Designed to address the needs of competition shooters and precision builders, it uses two large ventilated baffle sections and chambers to reduce felt recoil and help keep the rifle stable during rapid, consecutive shots. Its first chamber wall is designed to sit as close to the barrel crown plane as possible to help preserve barrel accuracy, while two top ports machined at a 20-degree forward angle direct gas energy to promote a flatter, more controllable muzzle impulse.Product HighlightsFATman Hex Brake muzzle brake for .223 Remington / 5.56x45mm NATO AR-platform riflesTwo large ventilated baffle sections and chambers help reduce felt recoil and improve controlTop ports machined at a 20-degree forward angle to help keep the muzzle flatter shot-to-shotBlack parkerized steel construction for durability and a mil-spec style finish1/2"-28 threads (threads-per-inch) and 3" overall length for common AR-15 compatibilitySpecsBrand: Phase 5 Weapon SystemsManufacturer Part Number: FATMAN556UPC: 813318021502Type: Muzzle BrakeCaliber Compatibility: .223 Remington, 5.56x45mm NATOPlatform Compatibility: AR-platformThread Pitch: 1/2"-28 (threads per inch)Overall Length: 3 inMaterial: SteelFinish: Black ParkerizedDesign Features: Two ventilated baffle sections/chambers; two top ports at 20-degree forward angleWidth: 1.26 inWeight: 6.1 ozIn the Box: Crush washerDisclaimer: We strive to provide accurate and up-to-date product descriptions, specifications, and images; however, errors or omissions may occasionally occur.
