Great weapon light - SureFire M640DF Scout Light Pro Dual Fuel LED Weapon Light

I haven't had a ton of time to put it through it's paces, but so far it's been great. I used the M-lok adapter and everything mounted easily and was very intuitive. The light feels very sturdy and easy to swap parts on. The FDE finish is really nice if you're into the more matte finishes (which I am). My only complaint, and the reason I couldn't go to the full five stars, is the price. I think the light is really nice, mounts easily, and can hold it's own, but I wish they were priced a bit more competitively.
