Worth every single penny. I bought this with all the parts for my AR build 3 months ago. Been running the light on this pistol for 750 rds, no problem. Bright, clear, long-lasting battery life.

    Very nice flashlight. It’s a bit big, but I couldn’t find one with the features I wanted at the size I preferred. It tends to hang up on the holster provided when pulling out/putting in.

    Fenix set the bar and surpassed it. There’s no other flashlight manufacturer even close.
