The Yankee Hill Machine YHM 30 LT(A) Phantom Q.D. Muzzle Brake (YHM-4302-MB-28A) is a quick-detach muzzle device engineered for .30 caliber host firearms and for use with YHM’s Phantom Q.D. sound suppression systems. It provides a dedicated Q.D. mount interface and reduces felt recoil when the suppressor is not installed.
