The LSS Gen 3 chassis from MDT was built to be modular right down to the back end, and this Carbine Buttstock Interface is the piece that lets you bolt a standard AR-15 buffer tube onto the rear of your chassis. That opens up a huge range of stock options, since just about any carbine or precision stock that threads onto a mil-spec receiver extension will work here. If you already have a favorite AR stock or want that familiar collapsible feel on a bolt gun, this is how you get there.
The LSS Gen 3 is a build-your-own platform. You start with the chassis base for your action, then pick your buttstock interface, and this carbine version is one of three main choices alongside the XTN and Picatinny rail options. Once it's mounted, you thread on your buffer tube and stock, add a grip and forend, and you've got a complete rifle set up exactly how you want it. Because everything is interchangeable, you can go from a compact truck gun to a long-range rig by swapping parts down the road instead of buying a whole new setup.
MDT machined this interface out of 6061 aluminum and finished it in black Cerakote, so it holds up to real-world use and matches the rest of the LSS Gen 3 lineup. The fit is tight and the swap is quick, which makes it easy to reconfigure the rifle when your needs change. It also plays nice with AR-pattern grips, so your ergonomics carry right over from any AR you already run.
The big draw here is flexibility. Running a carbine interface means you can drop on a collapsible stock for adjustable length of pull, or move up to a full-featured precision stock when you want more adjustment. It's a smart pick for anyone building a compact carry rifle, a range toy, or a do-it-all bolt gun that borrows the best parts of the AR world.
It mounts to the rear of your LSS Gen 3 chassis and gives you a standard AR-15 buffer tube attachment point. From there you can thread on a mil-spec buffer tube and run nearly any carbine or precision stock built for the AR platform. It's the piece that lets a bolt-action chassis take advantage of the huge AR stock market.
Yes. This is a component of the modular LSS Gen 3 system, not a standalone chassis. You'll need the LSS Gen 3 base for your action, and then this interface bolts on as your chosen buttstock mount.
No, the interface itself ships with the mounting hardware needed to install it. You'll supply your own AR buffer tube and the carbine or precision stock you want to run. That's part of the appeal, since it lets you pick the exact stock that suits your build.
Absolutely. The LSS Gen 3 was designed so you can swap buttstock interfaces in minutes without pulling your barreled action. If you later decide you want a folding stock or MDT's XTN interface, you can change over without redoing the whole rifle.
