Do Remington 700 clone actions work with an MDT chassis?

Yes, as long as the action shares a true Remington 700 footprint it will work with any of our Remington 700 chassis systems. However, if the manufacture has changed things like lug configuration further tuning maybe required for proper function. This list is not final and we will continue to add to it as we can.

Zermatt Arms  TL3
