1/2-28 Extended Flash Hider for 13.7" Barrels - .223/5.56 - 37595

Engineered specifically for 13.7-inch barrels, the 1/2-28 Extended Flash Hider delivers the additional length needed to achieve a 16-inch overall barrel length when properly pinned and welded, while effectively reducing visible muzzle flash on .223/5.56 platforms. This manganese phosphate-finished device combines proven A2-style flash suppression with a compact, durable design that supports reliable performance in tactical and range environments.

Key Features

• Extended length design – Adds the precise extension required for legal compliance on 13.7-inch barrels after pin-and-weld installation
• 1/2×28 threading – Standard compatibility with most .223/5.56 AR-15 barrels for straightforward installation
• Manganese phosphate finish – Provides corrosion resistance and a low-reflectivity surface suited for tactical use
• Pre-drilled pin hole – Facilitates secure pinning and welding for permanent attachment
• 3.3 oz weight and compact dimensions – Minimal impact on overall firearm balance and handling

Benefits for Shooters

By dispersing propellant gases outward, this flash hider helps maintain a clear sight picture during rapid fire or low-light conditions. Its extended profile solves the common challenge of achieving compliant overall length on shorter barrels without sacrificing the maneuverability of a 13.7-inch platform. The robust construction ensures long-term durability under repeated use.
