The YHM Phantom 5.56mm Q.D. Flash Hider in 5/8×24 is the muzzle-end piece for YHM’s legacy 5.56mm Q.D. sound suppressors, and it also accepts YHM’s .30 caliber sound suppressors. It keeps the flash-hiding performance of the original Phantom flash hider, with a five-port design that decreases visible flash. An external locking mechanism keeps heat away from the spring mechanism of the quick-detach mount. YHM machines it from 4140 steel with a black oxide finish and builds it in the USA. This listing is the 5/8×24 version; YHM cuts the same hider in other thread sizes as well.
