From the manufacturer

Upgrade your .30 caliber rifle with the Breek Arms Plan B .30 Cal 5/8x24 Sentinel Closed Flash Hider, the ultimate solution for discreet and effective muzzle management. Designed for shooters who demand low-signature performance without compromising on durability, this closed-tine flash hider significantly reduces visible muzzle flash, keeping your position concealed during low-light operations or tactical scenarios. Crafted from premium 4140 hardened steel with a robust nitride finish, it withstands the rigors of high-volume shooting while maintaining a sleek, snag-free profile. Key Features Superior Flash Suppression: The fully shrouded, closed-tine design disperses and redirects combustion gases, minimizing flash by up to 90% compared to standard birdcage hiders, ensuring night vision compatibility and reduced eye strain for you and your team. Plan B Compatibility: Engineered specifically for Breek Arms Plan B mounts, it offers seamless integration with suppressors and quick-detach systems, allowing for versatile setups without alignment issues. Pin-and-Weld Ready: Ideal for SBR builds or extending short-barreled rifles to meet federal 16-inch length requirements, providing a secure, permanent attachment option for compliance and stability. Compact and Lightweight: At just 1.8 ounces and 2.15 inches long, it adds minimal weight or bulk, preserving your rifle's balance and maneuverability in dynamic environments.
