Yankee Hill 444524 sRx Q.D. Flash Hider 5/8x24 Black Phosphate

The Yankee Hill 444524 sRx Q.D. Flash Hider delivers rapid suppressor attachment capabilities while maintaining effective muzzle flash reduction for tactical applications. This short-profile flash hider integrates seamlessly with Yankee Hill's sRx quick-detach suppressor system, eliminating the need for separate mounts or adapters.

What Makes This Different

Unlike standard flash hiders that require removal for suppressor mounting, the sRx Q.D. system allows instant suppressor attachment without tools or thread protectors. The short profile reduces overall barrel length by 0.75 inches compared to standard sRx mounts while maintaining full flash suppression effectiveness. Phosphate coating provides superior corrosion resistance compared to basic parkerizing, extending service life in harsh environments.

Key Features

• Quick-detach compatibility with all sRx suppressor models
• 5/8"-24 TPI threading fits .308/7.62mm and larger calibers
• Black phosphate finish resists corrosion and wear
• Short 1.5-inch length minimizes barrel extension
• Steel construction handles repeated suppressor mounting cycles
• Closed-bottom design prevents debris accumulation
• Precision-machined threads ensure proper suppressor alignment

Field performance remains consistent across temperature extremes and high round counts. The steel construction withstands the thermal stress of rapid-fire sequences while maintaining dimensional stability for accurate suppressor indexing. Law enforcement and military users report reliable function through 5,000+ round service intervals without thread wear or timing issues.
