MDT LSS GEN3 Chassis System-Tactical

Product Description

ONE RIFLE. ENDLESS ROLES.
Need a rifle that can handle just about anything? Start with the MDT LSS Gen3 Tactical Kit. It’s built for rugged performance, everyday reliability, and rock-solid flexibility—whether you're running it as a truck gun, a backcountry bolt rig, or your weekend range toy.

With the familiar ergonomics of an AR-15 and the precision of a bolt-action, this kit delivers serious capability—and leaves plenty of room for upgrades.

BUILT TO TAKE A BEATING
This isn’t a showpiece. It’s a workhorse. The Tactical Kit features a rigid, no-flex forend and a fit that holds zero no matter how rough you get. It’s ready to ride in the back seat, hike into the brush, or take a tumble on the line.

READY FOR WHATEVER COMES NEXT
This isn’t about being lightweight or stripped down—it’s about being ready. Tactical applications, all-purpose field builds, or that “do-it-all” setup you’ve been chasing—it starts right here.

ADJUST ON THE FLY
Outfitted with the SCS Buttstock, you get fast, tool-free adjustments for length of pull, cheek riser height, and buttpad position. Get locked in, fast.

MODULAR FROM FRONT TO BACK
The Tactical Forend gives you M-LOK on all five sides—perfect for mounting bipods, slings, weights, lights, or whatever your loadout demands.

A PLATFORM THAT GROWS WITH YOU
This is a pre-configured kit, sure—but it’s still the highly modular LSS Gen3 at its core. Swap the grip. Change the stock. Upgrade the forend. Whether your mission changes or your tastes evolve, this chassis system keeps up.

MDT LSS Gen3 Tactical Kit—because your rifle shouldn’t be boxed into one role.
