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). Available in the following; .223 / 5.56, .308 / 7.62 and 350 Legend.

Installation Instructions For Crush Washer:
- Inspect and clean threads on barrel and muzzle device.
- Place the crush washer cone forward over the muzzle threads, then thread the muzzle device up against the crush washer.
- Hand tighten the muzzle device and note that crush must be flush with barrel shoulder and fully depress the detent.
- Using a wrench, turn the muzzle device 1/4 turn, then continue to tighten to index properly. If the muzzle device is tightened past desired position, start over with a new crush washer.
- Check concentricity with a bore alignment rod.
- Test fire at 25 yards into a paper target backed up by a minimum 15′ x 15′ safety berm capable of safely stopping projectiles. Verify the ability to shoot groups and inspect for baffle strikes for all loads that will be used.
