MDT Stalker Core Buttstock Now Available: Lightweight, Minimalist, and Modular

First unveiled at SHOT Show 2026, the MDT Stalker Core Buttstock is now officially available for purchase, bringing MDT’s minimalist approach to shooters seeking a lightweight, rigid, and highly adaptable buttstock for XTN-compatible Chassis Systems. The Stalker Core was designed around a straightforward idea: remove unnecessary weight and bulk while retaining the strength and modularity shooters expect from an MDT buttstock.

At just 9 ounces, the Stalker Core provides a stripped-down foundation that can be run exactly as it comes or upgraded with additional components as a shooter’s needs change. Whether you’re putting together a lightweight hunting rifle, compact night-hunting setup, or simply want to reduce the size and weight of an existing chassis system, the Stalker Core delivers the essentials without unnecessary complexity.

Minimalist, Lightweight, and Built to Grow

The Stalker Core uses MDT’s XTN interface, allowing the buttstock to mount directly to all MDT XTN chassis systems and compatible folding adapters. Built around a rigid Cerakote-finished aluminum skeleton with a narrow overmolded buttpad, the Stalker Core measures just 8.5 inches long, 1 inch wide, and 5 inches tall, and weighs only 9 ounces.

Its compact design also provides an ultra-short length of pull, making it well-suited for lightweight, compact rifle builds as well as for shooters wearing heavy clothing or additional equipment. Depending on the chassis and XTN interface, LOP ranges from 10.43 inches on an LSS Gen3 R700 with the Short XTN Interface, to 11.36 inches with the Regular XTN Interface, while an ACC Premier Gen2 R700 SA measures 11.2 inches.

Despite its minimalist design, the Stalker Core isn’t locked into a single configuration. MDT designed it as a modular foundation that can be upgraded as a shooter’s needs change. The buttstock is compatible with the Stalker Cheek Riser, Stalker Buttstock LOP Spacer, and QD accessories, allowing shooters to add adjustment and functionality without replacing the entire system.

For hunters and shooters who prioritize weight and simplicity, that means the Stalker Core can be run in its lightest, most compact configuration from the start, then expanded with additional length of pull, cheek support, or sling attachment options when needed.
