Dead Air KeyMo Flash Hider | .30 Cal | M14x1 LH

The Dead Air KeyMount (KeyMo) flash hider is a suppressor-compatible muzzle device for .30 caliber firearms with M14x1 LH threads. Its mass-shifted, equal-length tine design is intended to eliminate the characteristic ping associated with some flash hiders when used with Dead Air KeyMo-equipped suppressors. Built from 4140 HT alloy steel with a black nitride finish, the unit prioritizes durability and reliable attachment to KeyMo and KeyMicro devices.

Common applications include mounting KeyMo/KeyMicro-compatible suppressors for precision shooting and range/competition use where a secure, repeatable interface is required.
