The Ultradyne Athena Linear Compensator for AR-10 308 Winchester 5/8x24, Black is a muzzle device that fits AR-10s with 5/8X24 Threads.
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.
A muzzle device reduces flash or recoil and muzzle rise, depending on its design. Check the thread pitch matches your barrel exactly, and time the device with a crush washer or shims as the manufacturer instructs.
