Element AN/PEQ-16A Pointer Illumunator Aiming Flashlight Black
[AS2653]

This thing is superb, the light is blinding and the laser is awesome. It fits perfectly on the rail with no wobble. I have it on the left side of my gun with the pressure pad on the side of my forward grip. I don't suggest putting this thing on the top of your rail because you can't see through your scope/iron sights very well.
Pros
1. Looks great, matt finish and stickers.
2.Very solid no wobble.
3.Flash light bright and crisp.
4. Pressure plate easily removed and installed.
Cons
1. Can't have multiple lights on at once.
2. Had to super glue velcro to pressure plate to stop it coming off.

All in all I would definitely recommend this product. It will help you no end.
