The MDT STS Buttstock LSS Gen3 Black Rubber brings a familiar, traditional rifle feel to the modular MDT LSS Gen3 chassis system. This skeleton traditional stock combines a rigid aluminum frame with overmolded rubber grip surfaces and an adjustable foam cheek piece, giving shooters a solid rear stock option that still feels like a classic rifle.

Designed specifically for LSS Gen3 builds, the STS Buttstock offers adjustable length of pull via included spacers, a comfortable semi-pistol grip profile, and integrated M-LOK and QD sling mounting points. It is ideal for precision-focused range work, practical competition, and general training where repeatable comfort and stable cheek weld matter. The design reflects MDT’s reputation for thoughtful ergonomics and consistent, chassis-level performance.
