I have one of your new T-series 9 inch rail I purchased for a build in January, its built great and is lightweight. Here is the problem, the whole upper has been built and is sitting useless because my builder ordered the proprietary wrench from your website in friggin JANUARY and still has not received it yet! I cannot find one anywhere myself and no other wrench at any of the gunsmith's in my area seem to work. I tried using the punch method described here in the forum and the ring is loose after a few shots. If I knew this was going to be such an ordeal I would have purchased something else. What are my options? Do you guys even make the wrench anymore? I'm really pissed that its September and I STILL cannot use this gun! Any help would be greatly appreciated. Dan
