MDT LSS Gen 3 Chassis System for Ruger American Short Action – Black (115052BLK)

Upgrade your Ruger American Short Action rifle with the MDT LSS Gen 3 Chassis System in black. Engineered for precision shooters and tactical competitors, the LSS Gen 3 represents a significant evolution in MDT’s proven chassis line, delivering enhanced ergonomics, modularity, and rock-solid rigidity right out of the box.

The LSS Gen 3 chassis replaces your factory stock with a fully adjustable aluminum frame designed to accept standard AR-15/M16 pistol grips and a wide range of folding and fixed AR-compatible buttstocks, giving you complete control over your fit and shooting position. The right-hand tactical configuration is purpose-built for serious shooters who demand consistent, repeatable performance on the range or in the field.

Key features of the MDT LSS Gen 3 include a robust aluminum receiver bedding block for improved accuracy and consistency, a fully adjustable length-of-pull and cheek weld when paired with compatible stocks, ARCA rail compatibility for tripod and support systems integration, M-LOK attachment points for accessories, and an ergonomic design that promotes a natural shooting stance for long-range precision work.

Whether you’re building a dedicated PRS competition rifle, a long-range hunting rig, or a high-performance tactical platform, the MDT LSS Gen 3 is a top-tier foundation for your Ruger American build.
