MDT LSS 22 RIFLE CHASSIS SYSTEM

MDT LSS 22 Rifle Chassis System Details

The Modular Driven Technologies LSS 22 Rifle Chassis System for .22LR caliber rifles is lightweight and compact, and adopts the same footprint as the centerfire MDT LSS Rifle Chassis. 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 LSS 22 Rifle 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, MDT has designed designed the rifle chassis to take collapsible AR-15 buttstocks. Fixed buttstocks can also be mounted with the use of a fixed stock adapter.

The LSS-22 uses your factory magazine and each chassis is compatible with all factory barrel contours.

Because we have lowered the buttstock interface, 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.
