Dead Air KeyMo Flash Hider Features The Dead Air KeyMo Flash Hider is machined from 4140 HT alloy steel with a black nitride finish that delivers exceptional surface hardness and corrosion resistance through sustained hard use on duty and training platforms. The mass-shifted equal-length tine design disrupts and cools burning gases before they ignite outside the muzzle reducing visible flash signature in low-light conditions where muzzle flash matters most. Unlike traditional 3-prong flash hiders the tine geometry eliminates the audible ringing effect during firing and handling without compromising flash reduction performance. Precision-machined geometry provides consistent suppressor lockup and alignment with every KeyMo-equipped suppressor installation delivering a non-negotiable return to zero that precision and duty shooters demand. The M14x1 LH thread pattern and 4140 HT alloy steel construction make this KeyMo system flash hider equally capable as a standalone muzzle device and a reliable suppressor mounting solution across a wide range of .30 caliber rifle platforms.
