ESS Howa Long Action Folding Chassis – Burnt Bronze


Out of stock



The ESS is our favourite MDT chassis here at The Gun Rack. Kassie runs a short action burnt bronze ESS on her Howa 1500 6.5 Creedmoor, and Geoff swaps a black long action version across various magnum and long action builds. Usually these chassis are purchased as individual parts, however we’ve put together a full package and knocked some off the price (just choose the mag and grip you need). The MDT factory Cerakote options usually add a 4 – 6 week lead time on the already lengthy waits for oversees products to land in New Zealand, so this is an opportunity not to be missed!

The ESS provides ultimate ergonomics and features!

The MDT ESS chassis is designed with its own buttstock for perfect ergonomics, and allows for customization with a wide variety of accessories.

This ESS Chassis System includes chassis, folding buttstock, and 18″ no rail forend.


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 AR pattern 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.

The MDT ESS chassis comes with its own butt-stock, similar to our Skeleton Rifle Stock. 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.
