Yankee Hill 440528 sRx Q.D. Flash Hider 1/2x28 9mm Long Black

The Yankee Hill 440528 sRx Q.D. Flash Hider delivers rapid suppressor attachment capabilities with enhanced muzzle flash reduction for 9mm firearms. This extended-length flash hider integrates seamlessly with Yankee Hill's sRx suppressor system while providing effective flash suppression during unsuppressed firing.

What Makes This Different

Unlike standard flash hiders that require tools for suppressor mounting, the sRx Q.D. system enables tool-free suppressor attachment and removal in seconds. The extended 2.30-inch overall length provides additional thread engagement and improved gas seal compared to shorter alternatives. Black phosphate coating offers superior corrosion resistance over standard parkerizing, maintaining performance through thousands of rounds and harsh environmental conditions.
