The IWI Left-Hand Quick-Detach Flash Hider (brand part no. IWSQDFH28) threads onto a 1/2×28 muzzle and does double duty as both a standalone flash hider and the mounting interface for a compatible IWI quick-detach suppressor. The left-hand threading is used specifically to prevent the device from backing off under recoil. Run bare, it reduces visible muzzle flash; with a compatible IWI suppressor attached, it becomes the fast, tool-free mounting point. This is a factory-matched piece within the IWI QD suppressor ecosystem, not a universal muzzle device.

Key Specifications

• Cut to a 1/2×28 thread pitch in a left-hand orientation to prevent backing off under recoil.
• Functions as a flash hider when run without a suppressor attached.
• Doubles as the quick-detach mounting interface for compatible IWI suppressors.
• Weighs approximately 3.49 ounces, adding negligible weight to the build.
