Vortex Strikefire II ARD KillFlash
Reduce objective lens glare and reflection on any threaded Strikefire red dot scope with this compact, anti-reflection device (ARD). In addition to reducing reflection, the threaded ARD protects the lens from scratches and damage.

The Vortex Strikefire II ARD KillFlash honeycomb mesh to significantly reduce glare and light reflection from the front of the optic, helping prevent lens flash that could give away your position in bright conditions. In addition to glare reduction, it offers light protection for the objective lens against scratches and debris, installs easily by threading directly onto the optic, and remains compatible with flip-up lens covers. Like other Vortex accessories, it’s backed by the company’s VIP lifetime warranty and is commonly used for tactical shooting, training, and hunting where reflection control matters.
To add or remove the ARD:

Remove the flip cap from the StrikeFire.

Thread the ARD into/out of the objective lens barrel.

Push the flip cap back onto the StrikeFire.
