This light will fit anywhere...a pistol, and AR, anything with a rail. It's bright enough to illuminate a large room, and can even light up a forest if you need light to navigate. It's also lightweight, and built tough. I am very pleased with it, and have one of these on every piece of gear with a rail that I own!
Pros: Small, bright, tough
