This is a remix of unseenkillers little giant foldout stock rail mount. I altered it to work with my PDW remix which allows for two 35mm M5 bolts to join the two pieces. This has been tested and is extremely sturdy. For the rest of the files, a hardware list and instructions, please find his repository.
