Pretty sweet by Nevertoomany895, Verified Owner, January 16, 2022
So I was on the fence on whether or not to get this, and I'm mostly glad I did. Hider is well machined and very nice. The only thing keeping it from five stars in my case was the Ultradyne logo had some color loss, like the lasering was a blem. But w...

Excellent flash hider for a bit of extra length by Pelt, Verified Owner, December 13, 2022

Product Info for Ultradyne Nighthawk Flash Hider, .223/5.56

Nighthawk is a birdcage style flash suppressor, engineered to reduce muzzle flash that can impair the eye's night vision in low light. Additionally a solid undercarriage decreases the chance of a dust cloud forming while shooting from a prone position. The Nighthawk also reduces muzzle rise which results in faster follow-up shots with increased accuracy. Like all Ultradyne muzzle devices, a timing nut is included for easy installation.image
