I was thoroughly impressed by the light for its price. I was also pleased to find that Streamlight includes all the necessary accessories with the light- batteries, remote switch, rail mount clips for the remote switch, and zip ties and double sided tape to make sure it all stays put. The light is certainly bright enough to cast out to 300 yards, but the low setting allows for indoor use without "washout" or "whiteout" from excessive brightness. It comes factory set at High/Strobe, but I suspect Law Enforcement users will prefer the Low/High option for indoor/outdoor use to avoid the issues I just mentioned. I will admit that I am partial to Streamlight products over Surefire, partly because of the lower price point and partly because I've seen several Surefire lights fail during classes. I can't justify the price for a light that isn't any more reliable. I would prefer the option to use a rechargeable battery, but Streamlight advises only using standard Lithium batteries in the Rail Mount 2.
Overall, the Streamlight ProTac Rail Mount 2 is a solid light. I currently have one mounted on a demo rifle for customers to check out and fondle. Be sure to ask about it the next time you find BBR at a trade show or event and see for yourself.
