YANKEE HILL MACHINE COMPANY MUZZLE BRAKE MINI 30CAL 5/8-24

Description

The Mini Phantom Q.D. Muzzle Brake is built for shooters running a Yankee Hill Machine suppressor system who want the shortest possible muzzle device without sacrificing suppressor compatibility or recoil management. At 1.6 inches long, it adds far less forward weight and overall length than a full-size Phantom mount, which matters when barrel length is already a consideration or when the rifle needs to stay as compact as possible.

The Q.D. interface is the core of what makes this brake useful beyond simple flash or muzzle control. It accepts YHM fast-attach suppressors — including the Turbo T2, Turbo K, Resonator R2, Resonator K, and Phantom QD 7.62 — so the brake functions as a standalone muzzle device when shooting unsuppressed and becomes the mounting point the moment a suppressor goes on. That transition requires no tools and no thread protector to remove and pocket before a stage or in the field. A shim kit is included to ensure the brake indexes correctly and stays in position under the torque generated by sustained fire.

Construction is 4140 steel with a Black Oxide finish, which keeps weight down relative to heavier alloys while giving the part enough surface hardness to handle the thermal and mechanical stress at the muzzle. The 5/8″-24 thread pitch fits standard .30-caliber barrels. YHM specifies a torque range of 20 to 30 ft-lbs during installation — staying within that window protects both the brake’s indexing and the barrel threads. The through-bore is .350 inches, sized to clear .30-caliber projectiles with adequate margin.
