Radical Firearms
Overview
The Radical Firearms A2 Flash Hider is designed to effectively reduce the visibility of the muzzle flash when firing, making it a practical choice for those who want to maintain a low profile during shooting. With a standard 1/2x28 thread pitch, it easily attaches to most AR-15 barrels configured for 5.56 NATO, while the nitride finish provides enhanced durability and corrosion resistance. This flash hider is commonly found in mid-length gas system builds, offering both functionality and reliability for shooters.
