The Yankee Hill sRx Q.D. Flash Hider is a quick-disconnect muzzle device built for shooters who want a clean, minimal-length suppressor mounting solution without the hassle of timing and shimming. Engineered for 9mm and smaller caliber barrels, this 5/8"-24 tpi flash hider pairs with Yankee Hill's sRx adapter system to create a low-profile, repeatable mounting interface that locks in hard and stays sealed.
Built from 4140 steel with a black phosphate finish, the sRx flash hider is purpose-built to handle the rigors of suppressed shooting. The design incorporates an internal taper seal that forms a tight barrier against gas leakage and thread buildup—a real problem with traditional threaded suppressors. The taper design means no shimming or timing needed; mount it and shoot. At just 2.30 inches in length and 0.9375 inches in diameter, it adds minimal footprint to your barrel while delivering all the benefits of the sRx system when paired with compatible adapters. Whether you're running a dedicated suppressed 9mm or stepping down from a larger caliber platform, this flash hider delivers the aesthetics and ease-of-use that shooters expect from Yankee Hill's sRx line.
The sRx platform uses an industry-standard 1-3/8" x 24 HUB mounting interface, so your suppressor integrates seamlessly with other quality sRx components. No moving parts, no complex timing—just solid engineering that lets you focus on your shooting. If you're building a suppressed 9mm rig and want a muzzle device that does its job without drama, the sRx Q.D. flash hider is a smart choice.
