MDT LSS Gen 3 "The Tactical" Chassis
Built to work hard and adapt fast, the MDT LSS Gen 3 Tactical Chassis is a versatile bolt-action platform designed for shooters who want one setup that can do a little of everything—reliably.
Pete’s Pillars offers the LSS Gen 3 Tactical as part of MDT’s refined Gen 3 lineup, built around improved rigidity, cleaner interfaces, and a more solid overall feel compared to earlier generations. The result is a chassis that maintains consistent action support, holds zero under use, and delivers dependable performance across a wide range of real-world applications.
While the Gen 3 Competitor model leans fully into match-focused performance, the Tactical version strikes a balance between durability, flexibility, and shootability. It’s equally at home as a hunting rifle, a dependable truck setup, or a range rifle that sees regular use. And when the work week is over, it can be set up for PRS or NRL-style competition without missing a beat.
The M-LOK mounting interface allows you to tune balance and function with weights and accessories based on how you actually use the rifle. The LSS Gen 3 Tactical is built to take use without giving up accuracy—making it a true jack-of-all-trades for bolt-action shooters who value versatility and reliability.
