The GrovTec G-Nite Pronged Flash Hider (MPN: GTHM355) is an open-prong muzzle accessory engineered for .223 Remington and 5.56×45mm NATO calibre firearms. Machined from durable steel and treated with a protective black nitride finish, it threads directly onto standard 1/2"-28 TPI barrels using the included crush washer. The pronged geometry rapidly disperses and cools expanding propellant gases, significantly reducing visible muzzle flash signatures to preserve night-adjusted vision during low-light field applications.

Key Features

• Open-Prong Flash Suppression: Multi-prong design accelerates gas cooling and dispersal at the muzzle to minimise visible flash report.
• Thread Compatibility: Machined specifically for standard 1/2"-28 TPI muzzle threads on .223 Rem / 5.56mm platforms.
• Black Nitride Treatment: Protective finish enhances surface hardness, wear resistance, and corrosion protection against powder residue and outdoor exposure.
• Mechanical Installation: Non-powered, passive muzzle device supplied with a crush washer for proper timing and secure attachment.

Who is the GrovTec G-Nite Pronged Flash Hider for?

• Varmint and predator night hunters — who need an open-prong flash hider engineered to disperse burning propellant gases on .223 Remington / 5.56×45mm NATO platforms, preserving night-adjusted vision when engaging targets in low-light environments.
• Pest control shooters — who operate .223 Rem rifles threaded to 1/2"-28 TPI and require reduced visual muzzle flash signatures during dusk, dawn, or spotlighting operations.
• Target and range shooters — who want a durable, black nitride-finished steel muzzle device to protect the 1/2"-28 muzzle crown on their 5.56mm target platforms while cutting down peripheral flash.

Less suitable for: Shooters using barrels threaded for larger calibres such as 9mm or .30 cal / 7.62mm, as firing larger projectiles through a .223 Rem (1/2"-28 TPI) aperture causes catastrophic failure; users whose primary requirement is maximum recoil reduction or muzzle-rise mitigation should select a dedicated multi-port muzzle brake or compensator instead.
