ATHENA is Ultradyne’s linear compensator. Muzzle rise has been optimized, with gas vented at an angle then forward. This sends a lower percent of sound and gasses back towards the shooter, optimizing sonic performance over recoil. Athena gives a cleaner appearance for a sleek look compared to traditional brakes and is the most cost-effective way to upgrade a rifle to the Dynamount Sighting System. Like all Ultradyne muzzle devices, a timing nut is included for easy installation ( Crush washer for the .350 caliber).
