This is a customized PDW frame for a G17 glock, copied of an existing model. I remade it from scratch because of some of the mounting problems I foresaw with my G17. This is intended to be used with UnseenKillers "Little Giant" foldout stock. I altered his "picatinny rail mount" as well to couple with this frame. That will uploaded as well, and for the rest of the files you have to download his project.
