The Rearden FHD (Flash Hider Device) Tapered Shoulder Flash Hider is a precision-engineered muzzle device built for .375 caliber rifles with M13.5x1 left-hand threads, making it an ideal match for Sig MPX factory barrels. Machined from 17-4 PH H900 stainless steel and finished with a black nitride coating that achieves a surface hardness of 67 HRC, this flash hider delivers exceptional durability and corrosion resistance. The tapered shoulder design ensures full compatibility with Plan B type suppressor mounts, including the Rearden Atlas, Atlas XL, and Q Plan B, with no timing required during installation. This updated version features enlarged wrench flats on the rear for easier installation and secure torque application, ensuring a flush, square fit against the barrel shoulder every time.
