The LSS-RF (Rimfire) Chassis is based on our popular LSS Chassis system for rimfire rifles. The LSS-RF also fits 17 HMR or 22 WMR versions.
The 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.
The MDT LSS-22 chassis system is currently manufactured for the following bolt action rifle platforms:
Savage Mark II - compatible with 93R17
Anschutz Match 54 - compatible only with models 1710 and 1712
Anschutz Match 64 - compatible only with models 1416 and 1417
The LSS-RF now also fits 17 HMR or 22 WMR versions and will fit all heavy factory barrels.
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 can use iron sights
The CZ455 will not work with the CZ455 Tuning trigger
