The MDT ESS Chassis features MDT’s classic “V-Block” bedding system which allows a reliable and solid base for the rifle’s action. The refined magazine well allows for ease of magazine insertion and reduces magazine rattle and movement. The ESS Chassis also features a semi-flush Ambi paddle, easy to activate with either hand. Furthermore, EDT designed the recoil lug mortise to fit most aftermarket recoil lugs, and the trigger area to allow most aftermarket triggers.

MDT added a serrated barricade stop to the front of the magwell, and a forend grip at the balance point for comfort. The octagonal forend tube and wide foregrip area combine to allow many options for shooting with bags or improvised rests, and thumb shelves on both sides of the chassis allow shooting with an open grip.

The MDT ESS chassis uses a custom buttstock and buttstock interface, which allows placement of a standard AR pattern grip in an ideal relation to the trigger, but is still fully adjustable for lateral movement of the buttpad and cheek rest. Thumb screws allow height of the cheek rest and length of pull adjustments.
