Specifications

The Ultradyne UD11020 Nighthawk Flash Hider 7.62x39mm Black Nitride 416 Stainless S is engineered with specific ballistic needs in mind. It’s designed to effectively manage muzzle flash and control muzzle rise for the 7.62x39mm caliber, a popular choice for many AK-pattern rifles and their AR-platform counterparts. The device is constructed from 416 Stainless Steel, a material known for its excellent strength and corrosion resistance, making it ideal for components exposed to extreme heat and pressure. Its Black Nitride finish offers a durable, low-friction surface that also aids in preventing rust and wear. A key design element is its birdcage style with a solid undercarriage, which specifically targets the reduction of dust blow-back when shooting from the prone position. The inclusion of a timing nut is a thoughtful addition, simplifying the often-finicky process of correctly timing a muzzle device to a barrel, ensuring optimal performance and alignment.
