Mounts the FX Pocket Chronograph V2 to the underside of the barrel on the FX Impact M3 with Saber Tactical TRS top rail and barrel support installed.

Will also work without the TRS top rail.

I mounted the chrono with the grub screws then took it off and drilled small detents holes where you could see the screws where hitting for the grub screws to sit inside for a more secure fit.

In the future I want to extend it farther back between the barrel and bottle and support the barrel from the bottom as well.
