Well, I am hoping Surefire's customer service reputation is accurate. Light was holding a 6P LED on my M4, but broke the first time I opened it. It sat on the rifle through mild use for perhaps a month, under non-extreme conditions. Even if SF replaces it, I am buying a metal one for the future. I had a similar issue with SF flipopen IR and red filters - their plastic accessories don't seem to be built to the same durability standard as their lights. I DO NOT RECOMMEND.
Pros: hmm
Cons: Plastic clamp broke
