Must have for the o light - Olight M20 Warrior Premium Remote Pressure Switches - Straight/Curled

This is a must have if you want to mount your light on your AR. Amazing that it doesn't come with the O light, especially at the price of the light! At least it's low cost, and a must have at the price.
Pros: cheap price, well made, works perfectly
Cons: should come with the light
