I considered the Advanced Armament Corp (AAC) flash hider and the Smith Enterprise Vortex flash hider, both known for their flash suppression capabilities. Ultimately, I chose the SureFire SFA2-556-1/2-28 A2 Flash Hider for M4/M16 because of its dual role as a blank firing adapter and suppressor mount, coupled with SureFire’s reputation for unmatched quality.

Real-World Testing: Putting SureFire SFA2-556-1/2-28 A2 Flash Hider for M4/M16 to the Test

First Use Experience

My initial testing took place at an outdoor shooting range, focusing on both suppressed and unsuppressed fire. I used my M4 platform, alternating between standard ammunition and blank rounds. The weather was dry and sunny, providing ideal conditions for assessing flash suppression.

In unsuppressed fire, the SureFire SFA2-556-1/2-28 A2 Flash Hider for M4/M16 provided a noticeable reduction in muzzle flash compared to a standard A2 flash hider. With the SureFire SOCOM suppressor attached, the recoil impulse was significantly reduced, and the sound suppression was excellent. Switching to blank rounds, the adapter worked flawlessly with my Mil-Spec BFA, ensuring safe and reliable cycling of the action.

Installation was straightforward, thanks to the wrench flats. However, achieving proper timing required a bit of fine-tuning with shims. No major issues arose during the first range session, but I did notice a slight increase in muzzle weight with the suppressor attached.

Extended Use & Reliability

After several months of regular use, the SureFire SFA2-556-1/2-28 A2 Flash Hider for M4/M16 has proven its durability and reliability. There are no signs of excessive wear or corrosion, even after extended exposure to heat and carbon fouling. The stainless steel finish has held up remarkably well.

Maintenance is simple, requiring only occasional cleaning with a solvent and brush to remove carbon buildup. The adapter maintains a secure lockup with the suppressor, with no noticeable loosening or wobble. It outperforms standard A2 flash hiders in both flash suppression and suppressor mounting stability.
