LSS-RF Gen 2 Rimfire Chassis System is made after the LSS Gen 2 Chassis, with the same features and upgrades, but for 22LR / 17 HMR rifles and uses factory magazines. Lightweight and compact. Pistol grip and buttstock sold separately, MDT’s AR pistol grip and Skeleton Carbine Stock are good choises – but any AR pistol grip without beavertail and any AR stock with carbine buffer tube and castle nut will work.
