The MDT Control Bridge is an accessory for the ACC Elite chassis. It's designed to bolt on to the top of the forend to act as a mirage mitigation device, as well as a barrel cover when reaching up and over your forend for added recoil control.
Using the Control Bridge allows you to achieve an ergonomic grip with better recoil stabilization over the top of your forend. Also, you won't burn your hand when transitioning between positions on a stage.
Install using the pre-drilled holes on the top of the ACC Elite forend. Six screws fasten the bridge to the forend for a very rigid interface.
