When it comes to weapons, are you old school, or do you like new tech? There's no wrong answer, only something to consider. A design that has survived the test of time has a lot going for it. However, material, procedure, and designs all improve over time. Perhaps it is a good practice to embrace both the old and new when practical. This thought process brings us to the Next Level Armament Hi-Helix 9mm flash suppressor.

Forward To The Basics

Have you ever shot through an old MIL-SPEC, A2 Birdcage or three-prong flash hider? Have you ever done it in the dark, especially on full-auto? The flash signature, even with a 20-inch barrel is crazy. You can almost read by the light made by those old tried and true workhorses. I point this out, not to claim the old Birdcage flash hider is bad. It's just that things have gotten a lot better in the past half-century. Shoot through a Next Level Armament 9mm flash hider, and you'll throw that 60-year-old Birdcage down the hill.

Night-Blind At Noon

When you shoot in low-light, your night-vision suffers. Did you know that happens a little bit during the day too? Your eye is naturally drawn to the muzzle flash. You can’t help but focus on it with your peripheral vision. When this happens, you are not scanning for targets. It’s easy to develop tunnel vision. The Next Level Armament Hi-Helix 9mm flash suppressor reduces the effect on your vision caused by the muzzle flash. This flash may be from your weapon or your buddies gun firing by your side. Either way, the NLA Hi-Helix 9mm flash hider makes a difference.
