TAC21 Savage Chassis

The TAC21 Savage Chassis System by MDT is a combination of benchrest accuracy, superior ergonomics and specialized design. The TAC21 Savage Chassis brings the specified Savage Models (see below) to the next level in versatility and modularity, with an instant improvement in accuracy.

The TAC21 Savage Chassis System is manufactured out of billet 6061-T6 aluminum, which has been hard anodized to mil spec type III for extra strength, and has been finished with Cerakote™ in Black or Flat Dark Earth (FDE).

The TAC21 Savage Chassis is engineered to minimize warping and distortion. The rifle receiver only makes contact with the TAC21 Savage Chassis on the V shape bedding and recoil lug area insuring the best accuracy and repeatability. The generous clearance on the foreend makes any barrel (diameter up to the receiver size – 1.350”), free floating.

Inherently the TAC21 Savage Chassis has a straightline design, meaning that the recoil comes straight back instead of making the front of the rifle kick upwards. This results in more accurate and quicker follow up shots. This also translates to a decrease in felt recoil and comfort.


The TAC21 Savage Chassis is designed to accept any AR-15 butt-stock and pistol grip. The basic kit does not include shoulder butt-stock, magazine and pistol grip, offering the option to customize from the wide variety of accessories available on the market.

The TAC21 Savage Chassis uses external box style magazines in .223 and .308 caliber for Short Action and .300WM or .338LM magazines for Long Action rifles, and supports installation of bolt on MIL-STN-1913 accessory mounting rails on the fore-end and side of the action housing. Mounting holes are spaced for Magpul style L5 (11 slots) and L3 (7 slots) rails (1.600” / 3.200”).

With a top full length MIL-STN-1913 accessories mounting rail. The built-in mounting rail has 20 MOA (Minutes of Angle) on the action housing and is parallel to the barrel axis on the fore-end.

Note: Long action magazines come in 3 different lengths: 3.715″, 3.775″ an 8.050″. All TAC21 Long Action chassis use 3.715 magazines.

Important! This chassis will fit the following Savage modelsModel 10/110, 11/111, 12/112, 16/116

Models that will not fit:
12 Palma

The TAC21 Savage Chassis system comes as a 4-piece chassis, with all required mounting hardware included. This includes new action screws, and a screw for the pistol grip.

To complete this chassis on your rifle, the additional items you need to purchase are:

  • A buffer tube for your buttstock. (Both milspec and commercial work on the chassis)
  • An AR-15 Pistol Grip. Ideally without a beavertail, or use a soft (bendable) beavertail.
  • At least one magazine

For a lighter, more compact chassis, please also see the LSS Savage Chassis System or the HS3 Chassis System.
