MDT Releases LSS-XL Gen2 Chassis System


After many years in the field MDT’s LSS-XL chassis system has made a name for itself as a reliable and quality fixed stock chassis system. Looking back with pride at this success story, MDT is also looking forward and is equally proud to announce the release of its next generation of LSS-XL chassis system: the “LSS-XL Gen2”.

Time came to take the LSS-XL chassis system back to the drawing board where our team remodeled it, adding functional and aesthetic features, yet kept this LSS-XL Gen2 in line with the spirit of its predecessor to offer a reliable and accurate system to competition shooters.

Originally designed as a variant of our highly popular LSS chassis the LSS-XL was intended for use with fixed buttstocks and longer barrel systems. The LSS-XL Gen2 carries on with this design intent but also benefits from MDT’s years of chassis system design expertise. Features like our M-Lok compatible forend, integrated barricade stop, ambidextrous magazine latch and thumb shelf make for great additions to our V-shaped bedding and free floated forend features already present on the original LSS-XL. The LSS-XL Gen2 also comes in both fixed and collapsible configurations to adapt to any shooter’s buttstock preference.

A lot of thoughts were given to the aesthetic aspect as well and we believe that you will appreciate the more modern lines of the LSS-XL Gen2. But it is not just about looks. You can rest assured that the LSS-XL Gen2 stayed true to its essential attribute of being a lightweight (1.6-1.9 lb), multi-purpose chassis guarantying its users the agility they require in such a system.

The LSS-XL Gen2 can be customized with a wide range of accessories including any AR-15 buttstock and pistol grip, M-Lok rails and accessories as well MDT’s LSS-XL Gen2 Night Vision hood which adapts directly into the forend M-Lok slots. The LSS-XL Gen2 chassis are also compatible with AICS pattern magazines including our range of short action and long action MDT magazines.

So, whether this is your first introduction to the LSS-XL model or you’re already familiar with this stunning chassis system and are looking to upgrade, we look forward to counting you among the numerous LSS-XL Gen2 users and hearing from your personal experience of the system.

Our new LSS-XL Gen2 chassis system are available for various bolt action platforms and can be ordered at For more information about the LSS-XL Gen2 please visit our website and check our video.


  • Bug,
    I am sure this will be a nice upgrade on your Ruger American Predator. Regarding the tripod adapter, the one on the picture is from Magpul.
    In a couple weeks MDT will release its own M-Lok tripod adapters: one model will be specific to the LSS-XL Gen2 chassis and the other will fit any chassis.

  • Jim,
    The links to the LSS-XL Gen2 page have been fixed. You should be able to view our newest chassis now. Regarding the NV hood, the link will be updated in the next week or so.

  • Ordered up one of these for my Ruger American Predator. Nice looking chassis! It will be a welcomed upgrade from my old LSS. What tripod mount/adapter plate is that in your pictures?

  • Very interested! Would like to see more of the chassis and the NV Hood. All the links to the Gen 2 go to a 404 error page?

  • Jon,
    Regarding the return of your LSS-XL our standard return policy applies. If returned past 30 days of receiving your order you will be refunded (a 25% restocking fee applies). Seeing that your order is fairly recent we could do that for you.
    Otherwise we do not plan to have a “trade-in” of the LSS-XL for the LSS-XL Gen2.
    I hope this helps.
