This adapter plate is designed for the older style grip of the FX Impact MK2 & M3 and the FX Maverick as a mounting point for the Saber Tactical Bag Rider (ST0002).

When do you need this adapter?

FX used multiple grip types throughout the production of the FX Impact (MK2 and M3) and the FX Maverick.

Does your grip have a narrow channel that barely fits the mounting screw and a lip at the bottom? Then you need this adapter.

Later models with the UG1 grip, such as those on the Impact M4, Leopard, etc., do not require this adapter.
