Tango Down Grip Chip
Installation of the TangoDown vertical grip can be a challenge on some tight rails. You have to depress both locking bars while sliding the grip down the rail to the position you desire. Some of us have come up with ways to keep the locking bars depressed during installation, with tie wraps or sticks, for example. TangoDown has now come out with a little armorer tool called the Grip Chip made just for this purpose.
