The LSS-22 chassis system for .22LR caliber rifles is lightweight and compact, and adopts the same footprint as the LSS. You will notice a significant improvement in accuracy due to the V-shaped bedding and free floated fore-end, which allows for barrel contours up to 1" in diameter.

The chassis system is manufactured out of billet 6061-T6 aluminum, and has been finished with Cerakote™ in Black or Flat Dark Earth (FDE).

To keep this chassis system compact, it has been designed it to take collapsible AR-15 buttstocks. Fixed buttstocks can also be mounted with the use of a fixed stock adapter.

The LSS-22 uses the OEM magazine, and each chassis is compatible with all versions of its model (e.g. the 1712 chassis accommodates all Match 54 Anshutz).

Because the buttstock interface has been lowered, The Savage Mark II, CZ 455 and Ruger American are able to use iron sights with this chassis. If you are using a scope, we recommend a stock with a cheek riser.


The MDT LSS-22 chassis system is currently manufactured for the following bolt action rifle platforms:

  • Ruger American
  • CZ 455 & 452
  • Browning T-Bolt
  • Savage Mark II
  • Anshutz Match 54 (1710 & 1712 only)
  • Anshutz Match 64 (1416 & 1417 only)

Important Notes

  • The Ruger American requires the two OEM fixing components in addition to the magazine
  • The Browning T-Bolt requires the OEM magazine holder in addition to the magazine
  • The Savage Mark II, CZ 455 and Ruger American are able to use iron sights.


The LSS-22 chassis is designed to accept any AR-15 buttstock and pistol grip (purchased separately), and allows for customization with a wide variety of accessories.

Mounting holes are spaced for Magpul style L5 (11 slots) and L3 (7 slots) rails (1.600” / 3.200”) to be used on the bottom of the fore-end.
