MDT LSS Gen3 Ruger American SA RH FDE Chassis Base 114603-FDE

The MDT LSS Gen3 Chassis Base is the foundational component of MDT's modular chassis system, built specifically for the Ruger American Short Action platform in a right-hand configuration and finished in a rugged Flat Dark Earth Cerakote for a desert-tan tactical look. Machined from 6061 aluminum, it drops in without gunsmithing and accepts AICS-pattern magazines for reliable, repeatable feeding. As the core of the LSS GEN3 system, it supports interchangeable XTN, Carbine, and Picatinny buttstock interfaces along with a range of forends and grips, letting shooters reconfigure their rifle from a lightweight hunting setup to a fully weighted competition rig without ever removing the barreled action or disturbing their zero. At just 1.36 lb, the base keeps the overall build light while providing a rigid, precision-fit foundation for further customization. Backed by MDT's 30-day return policy and lifetime product support, it's the starting point for shooters looking to build out a Ruger American rifle in an FDE-themed setup.
