Yankee Hill 431528A Mini QD Flash Hider 5.56 NATO 1/2-28 Black

The Yankee Hill 431528A Mini QD Flash Hider reduces muzzle flash signature while maintaining the ability to quickly attach sound suppressors or other muzzle devices. This compact flash hider features a black phosphate finish and precision-machined steel construction for reliable performance on AR-15 platforms chambered in 5.56x45mm NATO.

What Makes This Different

The Mini QD design combines traditional flash suppression with quick-detach capability in a shorter overall length than standard QD muzzle devices. At just 2.13 inches overall, this flash hider adds minimal length to the barrel while providing the versatility of QD mounting. The black phosphate coating offers superior corrosion resistance compared to standard parkerizing, extending service life in harsh environments.

Key Features

• Quick-detach mounting system for rapid suppressor attachment
• Compact 2.13-inch overall length minimizes added barrel extension
• Black phosphate steel construction resists corrosion and wear
• Standard 1/2"-28 TPI threading fits most AR-15 barrels
• Optimized for 5.56x45mm NATO and .223 Remington cartridges
• Precision-machined flash suppression ports reduce muzzle signature
• Compatible with Yankee Hill Machine QD suppressors and adapters

Field testing demonstrates effective flash reduction during rapid fire sequences, particularly beneficial for low-light operations and night shooting scenarios. The QD mechanism locks securely under recoil while allowing tool-free removal when needed. Law enforcement and competitive shooters appreciate the ability to quickly transition between suppressed and unsuppressed configurations without barrel removal or specialized tools.
