The Yankee Hill Phantom Comp/Brake (brand part number YHM-28-5M1) is a 2.25-inch muzzle brake and compensator built for 5.56mm AR-platform rifles, redesigned from YHM’s popular Phantom flash suppressor body. The 5-port design skips a downward-facing port so it doesn’t kick up dust signature when firing from the prone position, and the 5M1 keeps the Phantom’s aggressive front-end teeth for a distinct look and feel over the smoother 5M2 variant. It threads onto a standard 1/2-28 muzzle and ships with a crush washer for a secure, properly timed installation. Note that this is a brake and compensator, not a flash suppressor; it will not reduce the firearm’s flash signature.
