Optic Lens Protection

Protect your optic lens from damage and scratches.


Simply screw into front of scope. Do NOT use any thread lock compounds.Carefully thread into the objective (front) of the optic. There is a risk of cross threading on finer threads. The ARD should screw in without any resisitance. Once the ARD is fully threaded and finger tight, continue to hand tight. Do not use thread sealants or tape. To remove, turn counter clockwise.


Treat the honeycomb grid with the same care you would any fine optical surface. If clogged with dirt or grit, remove ARD from optic and blow clean.

If necessary, run palin water through the honeycomb to clear it. Tap the killFLASH® housing lightly on a surface to clear excess water, then blow through it to remove the remainder and dry it. Reinstall ARD.

Camouflaging Your Gear

In critical counter sniper situations, the killFLASH® disk’s black honeycomb surface can be painted to match a camouflage scheme.

To do this, first remove the ARD from the scope. Moisten a small piece of foam, such as a sponge, with a camo paint somewhat lighter than the color effect you want to end up with. Lightly pat the surface of the honeycomb disk with the sponge.

Do not use so much paint that the cells are filled in; you only need to paint the surface. If you do get too much paint on it, tap the killFLASH® disk sharply face down on a piece of newspaper to clear the excess.
