ATHENA allows a shooter to inexpensively upgrade their rifle to the Dynamount Sighting System. Muzzle rise has been optimized as well with gas vented at an angle then forward. This sends a lower percent of sound back towards the shooter optimizing sonic performance over recoil. Like all Ultradyne muzzle devices a timing nut is included for easy installation.
