The ESS retains our proven V-block bedding system to form a solid and reliable base for the rifle action. The magazine well has been refined for easy insertion of the magazine, while reducing rattle and movement. The tab style magazine release has been replaced with a semi-flush ambidextrous paddle that can easily be activated by a weak or strong hand. The recoil lug mortise has been designed to accommodate most aftermarket recoil lugs, and the trigger area will accommodate most aftermarket triggers.

A serrated barricade stop has been added to the front of the magazine well, and a polymer forend grip at the balance point adds comfort. The wide fore-grip area combined with the octagonal profiled forend tube offers flexible options when shooting over bags or improvised rests.

Thumb shelves have been added to both sides of the chassis for shooters who prefer an open grip.

The most significant change is the incorporation of the ESS chassis specific buttstock interface, rather than the traditional interface. This allows us to place the pistol grip in optimum relation to the trigger, while still allowing the shooter to choose from the wide variety of AR pattern pistol grips which suit their preference.


A buttstock specifically designed for the MDT ESS chassis is available (sold separately), similar to our Skeleton Rifle Stock (note: only the ESS specific SRS will fit, not the regular SRS V5) It is fully adjustable including lateral adjustment for the butt-pad and the cheek rest. Cheek rest height and butt-pad length-of-pull are adjustable by thumb wheels.

Alternatively, an adaptor is available (sold separately) which will allow you to fit a Carbine buffer tube and a carbine buttstock to suit.


ESS Forends (sold separately) are offered in 3 different lengths, 12″, 15″ and 18″, can be ordered with a full rail, partial rail, or no rail with cut-outs to allow low scope mounting. Each forend comes with M-LOK slots and QD flush cup mounts. Action-specific scope mounting rails which co-index with the forend rail are available as an accessory.

The ESS Chassis System comes only as a chassis body and hardware.  You will need Allen keys to assemble and install on your rifle.

In addition to the ESS Chassis System, you will need:

  • MDT Skeleton Rifle Stock for the ESS Chassis (note: only the ESS specific SRS will fit, not the regular SRS V5)
  • MDT ESS Chassis System Forend
  • An AR pattern pistol grip, grips with a beavertail will require minor fitting
  • An AICS pattern magazine appropriate for the rifle chambering



This is the only action that we manufacture a chassis for that has a flat bottom action, so does not sit in a V-Block. For this reason, only MDT Polymer magazines and MDT Poly Metal magazines will work. The fitting may need to be modified slightly for proper feeding. For .223 models the bolt stop may be too long. This can easily be modified by removing the bolt stop and trimming the contact face.


For .223 models the bolt stop may be too long. This can easily be modified by removing the bolt stop and trimming the contact face.

You will need to remove the original magazine release housing and the housing locating dowel pin to install, as well as re-use the existing recoil lug from your stock.
