The Ultradyne Athena allows a shooter to easily 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. When combined with the Dynamount Flip-Up Front Sight users will benefit from the elimination of sight deflection association with handguard mounting.
