The MDT LSS GEN3 Chassis Base is the stripped-down core of MDT's modular LSS GEN3 system — the starting point for building a rifle exactly the way you want it.
This is the core chassis only: you add your choice of forend, buttstock interface, buttstock and grip.
Start light for hunting and later swap the forend and add weights for competition, or change the buttstock for different ergonomics. Parts change without pulling the action, so you keep your zero.
The base is made from 6061 aluminium with a durable Cerakote finish. The barrelled action simply drops in and is secured — no gunsmithing required. It takes AICS-pattern magazines and supports XTN, carbine and Picatinny buttstock interfaces.
