Next Level Armament Hi-Helix Flash Suppressor, 1/2x28 - NLX400
The NLX-5 Hi-Helix is Next Level Armament's flash hider for 5.56 AR-15s and the default muzzle device on its GFK complete uppers. Next Level turns each one from billet stainless steel in a single operation, then applies a Nextride QPQ coating and laser engraves the logo. The helical slot pattern is meant to hide flash from every viewing angle rather than just straight ahead.
It measures 2 inches long and 0.83 inches in diameter and threads onto standard 1/2x28 barrels with the included crush washer. It is a flash hider only, so a shooter who wants muzzle-rise control should look at the NLX-7 or NLX-9 instead.
