I am convinced these are out there and are being sold on Internet sites and at gun shows and such. I have only been able to speak to a few guys who have knowledge of this. These dealers share my conviction that some of the most popular light are being bootlegged. It is not a topic to bring up with the manufacturers of the lights that are being copied. I tired and got the company line on the topic. If these lights are out there as I believe they are then these companies have to know. Some guy buys a bootleg one, something goes wrong with it and he sends it in for warranty work. They have to know it is not theirs. They know the warranty registration number is fake. Would they repair these to keep the people from knowing this about their product being bootlegged? I am trying to find out as much as I can about this. A quick review of some leading auction sites shows several brands of weapons light being sold far below dealer cost. I am talking about the lowest cost any dealer can buy this product. So, the same product being sold consistently by the same guy at a price far below what he can buy it for is suspicious for sure. These products are ripe for this due to the cost, how small they are so that many can be shipped in to the country and the fact they are selling so well. I would even think that some high end optics could be involved. Any first hand experience would be helpful. I would prefer no name brands are mentioned as this could be unfair to that Manufacturer unless you have in your possession bootlegged product and can prove it is not original. Of course this is just my preference on the topic and guys will post what they choose to. I just believe that facts should be posted if a brand name is mentioned. Ideas from guys on how to avoid this such as buying from reputable dealers, known suppliers and from the Companies web site and other ideas would be welcomed also. I will take the best advice and offer it on my web site. Wanna kill these ads? We can help!
