MDT Releases LSS Chassis System for Mossberg Patriot SA


In 2015 Mossberg released a new line of bolt action rifle: the Mossberg Patriot. Since then the number of users of this inexpensive rifle keeps growing, proving that the accuracy Mossberg promised on their latest bolt action rifle was no myth.

Over the last couple years many of you have inquired if MDT had plans to release a chassis system for the Mossberg Patriot. With every new MDT product release, numerous requests poured in from shooters around the globe to be able to install their Mossberg Patriot in one of our renowned chassis systems to couple this rifle’s accuracy with the “out of the box” accuracy MDT’s chassis systems provide.

Since we are all about coming alongside bolt action rifle shooters to help them Shoot Better™ we are thrilled to announce that our LSS chassis system is now available for the Mossberg Patriot rifle chambered for short action calibers. The reason we chose our LSS chassis system is that it was specifically designed for short barrelled bolt action rifles (the Mossberg Patriot features a 22” barrel) and it is a compact chassis system which will not take away from the lightweight characteristic of the Patriot rifle.

You can now experience the increased accuracy that our chassis systems are known to provide with features like our “V-shaped” bedding and free-floating forend. The LSS chassis also features external box magazine feeding which will increase your magazine capacity from the 5+1 Mossberg magazine to the 10 rounds capacity of our MDT polymer or metal magazines or any AICS pattern magazines. The LSS is also designed to accommodate forend accessory rails and a multitude of different collapsible AR15 style buttstocks and pistol grips for further customization of your Mossberg Patriot rifle.

Increased accuracy. Better ergonomics. What better way to treat your Mossberg Patriot to a remodeled look and an increase in performance! MDT’s LSS chassis systems for Mossberg Patriot short action rifles can now be ordered at

    Yes, our LSS SA chassis will work for your Mossberg Patriot in 6.5 Creedmoor. Please note that our .308 magazines (5R & 10R) are also compatible with the 6.5 Creedmoor caliber.

  • I’m another one that wants a long action variant. All thats out there for the Patriot is a Boyd’s wood stock. If I wanted a wood stock I would have bought one. I have a .300 win and i would REALLY love to see her in a chassis..
