MDT LSS Gen3 Ruger American AR RH BLK Chassis Base 114609-BLK

The MDT LSS Gen3 Chassis Base is the foundational component of MDT's modular chassis system, purpose-built for Ruger American rifles configured to feed from AR-15 pattern magazines. Machined from 6061 aluminum and finished in durable Cerakote, it drops in without gunsmithing and gives AR-mag Ruger American owners the same magazine compatibility they're used to, now paired with a fully modular precision chassis. As the core of the LSS GEN3 system, it supports interchangeable buttstock interfaces, forends, and grips, letting shooters reconfigure their rifle between hunting, competition, and tactical setups 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 AR-mag Ruger American owners looking to upgrade their platform.
