MDT HS3 Chassis series is a combination of bench rest accuracy, superior ergonomics and specialized design. The new HS3 chassis brings your
bolt action rifle to the next level in versatility and ergonomics, with an instant improvement in accuracy. The chassis itself is only 2.47lb / 1.4kg and was designed based on customer feedback who wanted longer fore ends (3"/76mm longer than MDT LSS), and use fixed rifle stocks (as compared to MDT LSS chassis which was designed for compact use with collapsible stocks)

The drop-in chassis serves as a base to which the operator can add tactical components according to the desired functionality. The stock is manufactured
out of aluminum, hard anodized to mil spec type III, and has durable Polymer side panels which can be ordered in black or Flat Dark Earth (FDE).

This chassis was designed to accept Fixed AR-15 butt-stocks and non-beavertail pistol grips. The kit does not include shoulder butt-stock and pistol grip or magazines, offering the option to customize from the wide variety available on the market.

The HS3 chassis uses AICS style magazine in .300WM, 30.06 or .338LM and supports installation of bolt on MIL-STN-1913 accessory mounting rails on the bottom and sides of the fore-end. Spacers are required to mount side rails. The mounting holes are spaced for Magpul style L5 (11 slots) and L3 (7 slots) rails (1.600”/3.200”).

The rifle action only makes contact with the HS3 chassis on the V shape bedding and recoil lug area insuring the best accuracy and repeatability. The generous clearance on the fore-end makes any barrel up to the size of the action itself free floated.


  • Weight: 1.4kg/2.47lb
  • Designed for AR-15 fixed butt-stocks including our Skeleton Rifle Stock.
  • Accepts any AR-15 grip, without a beavertail.
  • Fits AICS / AM Magazines in .300WM and .338LM
  • Polymer sides in Black or Flat Dark Earth (FDE)

For rifles with the bolt release at the bottom, the bolt release can be engaged through the side of the chassis, using a pin or tool. (Not included)
Note: Savage has many different models and configurations. In a very few cases, small modifications may be neccesary to the chassis to ensure trigger group and recoil lug clearance.
