Nighthawk is a birdcage style flash hider, 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. 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.FeaturesMuzzle Flash Reduction100% CNC MachinedDynamount Ready416 Stainless Steel
