At last, a solution to the non MIL-STD 1913 rail problem. The VGI-001 Vertical Grip Adapter allows fast, rock-solid installation of all our standard BGV-series grips onto non MIL-STD 1913 compliant rails. This inexpensive fix is quality CNC machined from 6061 T6 aircraft aluminum, then Type III hard coat anodized for tough field use. Supplied fasteners are stainless steel, then black oxide finished. VGI-001 adds less than 1/2a ^2 of length to grip length over installation on MIL-STD 1913 Rails. Comes with full instructions and installation tool. Like all TD Inc. products, proudly made in USA.
