MDT SRS-X Lite Buttstock

• Adjustable fit: Spacer-based length-of-pull adjustment and a movable cheek riser let the rifle be set up to the shooter’s build and optic height, helping create a more repeatable head position behind the scope.
• Lightweight aluminum construction: The aluminium body keeps the buttstock rigid without adding unnecessary rear weight, which helps preserve a balanced rifle for field use or practical competition setups.
• Skeletonized structure: The open, reinforced design maintains strength while trimming excess material, giving the stock a solid feel without the bulk of a heavier rear assembly.
• XTN interface compatibility: Built for chassis systems that use the MDT LSS3 XTN Interface, it provides a purpose-made fit for compatible MDT platforms rather than a generic adapter-based solution.
• Accessory-ready layout: Features such as QD sling cups and a bottom M-LOK slot support practical rifle setup changes, from sling carry to rear support accessories for steadier shooting positions.

About the SRS-X Series

The MDT SRS-X Series sits in MDT’s line of precision-rifle buttstocks as a modular rear-stock platform built for shooters who want a more tailored fit than a basic fixed stock can provide. The series is aimed at target shooting, practical field use, and rifle builds where consistent body position behind the optic matters as much as raw stability. Across the family, the design emphasis is on adjustability, rigidity, and compatibility with MDT chassis systems that use the XTN interface.

A defining trait of the series is its focus on shooter interface. Adjustable cheek support and length-of-pull tuning help align the eye naturally with the optic, which supports faster sight picture acquisition and more repeatable recoil management. The SRS-X concept also favors a strong metal structure over a flexible polymer feel, giving the buttstock a more planted character on precision-oriented rifles. Depending on the exact model, the series can also support balance tuning and accessory mounting, making it suitable for rifles that need to be adapted for different disciplines, shooting positions, or optic heights.

About the MDT SRS-X Lite Buttstock

The MDT SRS-X Lite Buttstock is the lighter, simplified expression of the SRS-X concept, built for shooters who want the fit advantages of an adjustable precision buttstock without moving to a heavier competition-focused rear end. Its skeletonized 6061 aluminum construction gives the stock a firm, stable feel while keeping weight to 1.55 lbs (24.8 oz), which helps maintain a practical overall rifle balance on hunting chassis or crossover precision builds.

What makes this model especially useful is the way its adjustments support real shooting positions. The length of pull is adjusted with included spacers, allowing the rifle to be set up for body size, clothing layers, or prone versus barricade use. The cheek riser adjusts for height and fore-aft position, making it easier to establish a repeatable cheek weld with different scope mounting heights. That consistency matters in practice because it reduces the need to hunt for eye position behind the optic.

The SRS-X Lite also keeps the layout practical. QD sling cups support modern sling attachment, while the bottom M-LOK slot allows compatible accessories such as bag-riding solutions that can improve rear support on precision rifles. Designed around the XTN interface and compatible with the MDT LSS3 XTN Interface, it suits MDT chassis users who want a fixed buttstock with meaningful ergonomic adjustment and a rigid metal build.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada.
