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.


  • Lane,
    Glad to hear you are happy with your chassis system. Servicing our customers well is at the core of who MDT is and stories like yours encourage us to keep it that way.

  • Can’t thank these folks enough for their help in getting me a rifle system I can use. This system allows me to go to the range and shoot easily as being a disabled vet and an older shooter I needed to be able to handle my .308 with ease. This is the greatest system I’ve seen and everyone at the range asks where I got it! I spend more time giving out MDT info than shooting since I got this system. These are great folks that will help you get what you need, really they bend over backward to surprise you! Hands down you will not find a better system and the price is much more reasonable then any other I’ve looked at and I looked at a lot out there that did not want to work with me like these folks have. I highly dought you will find a better all-round system. I know you won’t find better people.

  • Chris,
    Yes you can definitely install the Magpul PRS stock on the LSS-XL Gen2 “Fixed”. Just note that in comparison to our SRS V5 stock which will give you a length of pull (LOP) of 13.5" on this chassis system, the Magpul PRS will give you a LOP of 14.5".

    I hope this helps.

    Julien Garnier
  • Looking at purchasing the Gen 2. Would the Magpul PRS stock be able to be attached to this chassis?

  • Jason,
    We are expecting to release the V5 buttstock by end of January 2018. You will not have to wait for too long.
