The Trijucon ACOG is an anti-reflection device (ARD) from Covert Arms is designed specifically for ACOG optics. Similar to a killflash, its design allows it to clip on internally to the optic itself, creating an extremely durable and easy to remove one-piece system. Created with anti-reflective material, there's no glint you'd get off of a traditional 3d printed version.
