M3x led - simply the best - EOTech M3X Tactical Illuminator Long Gun / Pistol Weapon Mounted Flashlight

This unit is awesome. It has held up to some serious abuse already, from being submerged in water to dropped onto hard surfaces. Battery life is on par with the rest of the field, the warranty cannot be beat. This is money well spent. Kudos to Insight Tech. You get what you pay for holds true here.
Pros: Indestructible, Incredibly Bright, Max Engineered, Easy to Mount
Cons: None so far
