The redesigned hinged KrissVector Folding Stock is compatible with both the GEN I and GEN II Kriss Vector (pre-2017) bodies and now features a metal sling loop below the body. The folding stock aids with the storage and transport of your KRISS Vector by reducing the overall length by approximately 9.5" when folded. Includes one pivot pin as pictured.NoteThis stock will not work with the Vector Gen 2-2017 which does not feature the original hinge mount.
