Cmmg Fh Fnh P90 Style M12 X 1 Lh

The CMMG Flash Hider for FN P90 Style M12 × 1 Left-Hand is a precision-engineered muzzle device purpose-built for short-barrel rifle builds chambered in the 5.7×28mm cartridge. This left-hand threaded flash hider delivers effective flash signature reduction while maintaining a compact profile—critical for SBR (short-barrel rifle) configurations where muzzle length and blast control directly impact operator effectiveness and situational awareness downrange.

The M12 × 1 left-hand thread pitch ensures secure, clockwise installation on compatible barrels, preventing accidental loosening during sustained fire. P90-style flash hider geometry minimizes visible muzzle flash—a critical advantage in low-light operations, indoor environments, and tactical scenarios where flash discipline preserves night vision and maintains concealment. At 0.19 lbs, the device adds minimal weight while managing recoil signature and redirect impulse, maintaining the velocity characteristics the 5.7×28mm cartridge delivers from short-barrel platforms.

This accessory is engineered for operators building PS90 SBR platforms and other 5.7×28mm short-barrel configurations where barrel length limits velocity and muzzle control becomes essential. The precision left-hand threading accommodates non-ambidextrous barrels found on many 5.7×28mm platforms. The P90-series flash hider design—proven across military and law enforcement applications—provides consistent performance in both suppressed and unsuppressed configurations, making it a versatile choice for carbine builds prioritizing flash reduction and compact ergonomics.
