MDT LSS Gen3 Ruger American LA RH BLK Chassis Base 114611-BLK

The MDT LSS Gen3 Chassis Base is the foundational component of MDT's modular chassis system, built specifically for right-hand Ruger American Long Action rifles. Machined from 6061 aluminum and finished in durable Cerakote, it drops in without gunsmithing and feeds from long-action AICS-pattern magazines. 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. Built to the same modular standard as MDT's short-action bases, it gives long-action Ruger American owners the same upgrade path in a chassis sized for their longer cartridge. Backed by MDT's 30-day return policy and lifetime product support, it's the starting point for building a fully modular long-action Ruger American rifle.
