The Ultradyne Athena Linear Compensator for AR-15s with 1/2x28 Threads, 223 Remington/5.56 NATO, 3.8 oz., 416 Stainless Steel, Black is a muzzle device that fits AR-15s with 1/2X28 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.
