CMMG 57DA5BE Flash Hider 5.7x28mm FN PS90 M12x1 LH Black Steel

The CMMG 57DA5BE Flash Hider is a purpose-built muzzle device designed for the FN PS90 platform chambered in 5.7x28mm. Machined from steel and finished in black, this compact flash hider threads directly onto PS90 barrels using the uncommon M12x1 left-hand thread pattern.

The 57DA5BE is a popular choice for PS90 SBR pistol builds where shooters want effective muzzle-flash control in a short, low-profile package. It matches the factory PS90 barrel thread specification, allowing direct installation on factory or aftermarket barrels cut with the correct M12x1 LH pitch.
