If you have any discarded electrical equipment, pull the copper from inside of the wires (very thin hair like wires, usually in head phones wire) and use a small piece under the front sight to lock it in place.

now that is cool, will have to save my pennies for this

so glad your back :) great video

love my fire sights

Thanks for the video. Their customer service is good but that design is poor and they should not have used that screw for elevation control. I have one of their sights and I will not buy another one, very poor design!
