Description
The MDT Tactical LSS Gen3 in black is a full chassis kit built to drop your Savage long action barreled action into a modern, modular platform. What makes the Gen3 stand apart from the older LSS chassis is its three-piece architecture: a center base cradles the action while the forend and buttstock adapter bolt to either end. That means you can rearrange the whole rifle for a different job without ever taking the action out of the base, and your zero comes right along with it.
What the Tactical LSS Gen3 Brings to a Savage Long Action
This configuration ships with the Tactical Forend, which carries M-LOK slots on all five faces for mounting a bipod, sling, light, weights, or spare rounds. The enclosed structure keeps flex out of the equation, so your bipod and barricade contact stay solid under load. Paired with that is the SCS (Skeleton Carbine Stock), giving you toolless adjustment for length of pull, cheek height, and buttpad position. Being able to dial in fit without digging for an allen key is one of those small things you appreciate the first time you set it up.
Built Around AR Familiarity and Real Modularity
The chassis accepts standard AR-style pistol grips, so it feels familiar if you spend time behind a modern sporting rifle, while keeping bolt-action precision. It comes with MDT's ambidextrous mag latch and runs AICS-pattern detachable magazines. There's a trigger adjustment slot and an integrated barricade stop on the forend, plus torque specs marked right under the forend to make assembly straightforward.
No Gunsmithing, No Bedding
Installation is genuinely simple. Drop in your barreled action, torque the screws to spec, and you're ready for the range with no bedding or gunsmithing needed. Because it's built on the Gen3 platform, the parts you get today aren't the end of the road. Want a longer forend for a heavier barrel down the line, or a different stock for a hunting build? Swap it and keep shooting. This is the do-it-all option in the LSS Gen3 lineup, built rugged for tactical use, truck carry, or a range rifle you plan to keep tinkering with.

Frequently Asked Questions
Will the Tactical LSS Gen3 fit my Savage long action rifle?
This kit is inlet specifically for Savage long action receivers, so it covers popular long action Savage models. If you're unsure whether your rifle is a long or short action, the safest move is to measure the distance between your action screws before ordering. Long action spacing differs from short action, and matching it is what guarantees a proper fit.
Do I need a gunsmith to install the LSS Gen3?
No. The chassis is a true drop-in design, so you set your barreled action into the center base, torque the screws to the marked specs, and you're ready to shoot. There's no bedding and no gunsmithing involved, which makes it a great first chassis build.
What magazines does the Tactical LSS Gen3 use?
It runs AICS-pattern detachable magazines and comes with an ambidextrous mag latch from the factory. It's also compatible with MDT's adjustable mag latch if you want to fine-tune fitment. For a long action rig, be sure to match your magazine length to your cartridge.
Can I swap parts on the LSS Gen3 later without losing zero?
Yes, and that's the headline feature of the Gen3 platform. Because the barreled action stays fastened in the center base, you can change the forend, buttstock, or grip without pulling the action, so your zero comes right along. It lets one chassis cover tactical, hunting, and range duty as your needs change.
