The Surefire 4-Prong Flash Hider for 5.56mm is a battle-tested muzzle device engineered to tame muzzle flash and serve as a rock-solid mounting platform for suppressor-ready rifles. Built on the design that won the most rigorous suppressor trial in military history, this flash hider delivers the signature reduction and reliability that matters downrange—whether you're running a precision AR-15, tactical carbine, or suppressed rifle setup.
Designed for 10-inch and longer M4/M16-variant rifles, the 4-prong configuration works to suppress visible flash by over 99% compared to a bare muzzle, dramatically cutting your thermal and visual signature. The design also eliminates first-round flash, a common issue with many suppressors. Precision-machined from U.S. mill-certified stainless steel and heat-treated for strength, it's built to handle full-auto use and years of hard shooting without degradation. Multiple bearing surfaces ensure proper suppressor alignment, making it a dependable mounting interface for any SureFire SOCOM Fast-Attach suppressor.
Tight tolerances and precision bore concentricity mean you don't sacrifice accuracy for flash reduction—the geometry is optimized for superior performance, not just looks. The Fast-Attach design allows tool-free installation and removal, keeping your workflow fast when swapping gear. Every unit is individually inspected for concentricity and alignment to guarantee the precision you'd expect from Surefire. Proudly made in the U.S.A. and backed by Surefire's No-Hassle Guarantee.

Frequently Asked Questions
Will this flash hider work with my suppressor?
The Surefire 4-Prong Flash Hider is designed as a dedicated mounting platform for any SureFire SOCOM Fast-Attach suppressor. Its multiple bearing surfaces ensure proper suppressor alignment and a rock-solid connection. If you're using a non-Surefire suppressor, verify that it accepts Surefire Fast-Attach mounts.
What rifle is this flash hider designed for?
This 5.56mm flash hider with 1/2x28 threading is optimized for 10-inch and longer M4/M16-variant rifles and carbines. The 6.4-inch length and four-prong geometry are engineered specifically for that barrel length range to deliver superior signature reduction.
Does this affect my rifle's accuracy?
No. Precision bore concentricity and tight tolerances are built into the design. Surefire flash hiders are individually inspected for alignment, and the geometry is engineered to maintain accuracy without point-of-impact shift.
Is this flash hider rated for full-auto fire?
Yes. The Inconel alloy and stainless-steel construction is durable enough to withstand full-auto use without degradation, making it suitable for both semi-auto and select-fire applications.
