MDT LSS-RF GEN2 RIMFIRE CHASSIS SYSTEM

Modular Driven Technologies as been releasing new products and next generation rifle chassis systems pretty regularly last few months and It really pleases me to see them giving Rimfire rifles their fair of attention. I’m a big proponent of MDT as their product quality is equal to their customer service. Modular Driven Technologies has been outstanding with regards to our sister site Modular Rifle and our rifle builds. To give you and idea of the popularity and quality of the MDT rifle chassis they are the chassis of choice that’s stock on many factory rifles today

MDT LSS-RF GEN2 CHASSIS SYSTEM DETAILS

Our LSS-RF 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 forend, 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, we have designed it to take carbine AR-15 buttstocks. Fixed buttstocks can also be mounted with the use of a fixed stock adapter.

The LSS-RF uses the 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 can use iron sights with this chassis. If you are using a scope, we recommend a stock with a cheek riser.

  • Ruger American
