One Horse A2 Bird Cage Flash Hider Features The One Horse A2 Bird Cage Flash Hider uses the classic bird cage geometry that has proven itself on 5.56 NATO rifles for decades directing and dispersing muzzle flash away from the shooter s line of sight. That reduction in visible flash helps preserve night vision and a clear sight picture during low-light engagements or extended strings of rapid fire. Threaded 1/2x28 the flash hider fits the standard thread pattern found on the vast majority of 5.56 NATO and .223 Remington AR-15 barrels giving it broad compatibility across builds. Built to Mil-Spec standards the flash hider meets the same dimensional and performance expectations as factory military hardware. A phosphate finish provides corrosion resistance and a non-reflective surface that holds up under field conditions and repeated handling. The flash hider ships with a crush washer which allows for secure properly timed installation without requiring a shim kit or additional parts. One Horse manufactures this flash hider in the United States giving builders a domestically produced option for completing a 5.56 NATO muzzle setup. For shooters upgrading or replacing a flash hider on an AR-15 build this A2 pattern hider from One Horse is a straightforward Mil-Spec compliant choice for sale at GrabAGun.
