MDT Rear Bag Rider, M-LOK

• Long rear support surface: The extended riding surface gives the buttstock more contact with a rear bag, helping the rifle track straighter under recoil and making small elevation corrections easier.
• Flat, horizontal profile: A level interface promotes more linear recoil movement, which helps precision shooters stay on target and spot impacts more consistently.
• Rounded snag-resistant shape: Smooth front and side contours reduce catching on bags, clothing, and range gear, so position changes are cleaner and less disruptive.
• M-LOK attachment: The M-LOK mounting format makes installation straightforward on compatible buttstocks and keeps the setup secure without adding unnecessary bulk.
• 6061-T6 aluminum construction: The aluminum body keeps weight modest while providing the stiffness and durability needed for repeated range use and hard field handling.

About the Rear Bag Rider Series

MDT Rear Bag Rider accessories are built for shooters who want a more stable and repeatable rear support interface on a precision rifle. In MDT’s lineup, this series sits among the company’s practical chassis and buttstock upgrades that refine how the rifle behaves from bags and improvised rests rather than changing the rifle’s core structure. The focus is simple: create a smoother, more consistent contact point between the buttstock and the rear bag.

The series is intended primarily for precision rifle shooting, whether on the bench, in positional practice, or in competition where recoil control and repeatability matter. Its defining characteristics are a flat riding surface, a rounded anti-snag profile, and mounting formats designed to fit compatible MDT buttstocks and related chassis setups. Rather than adding complexity, the design philosophy is to improve how the rifle settles and tracks. That matters in practice because a cleaner rear interface can reduce drag on the bag, support more predictable recoil movement, and make fine corrections easier when building a stable firing position.

About the MDT Rear Bag Rider, M-LOK

The MDT Rear Bag Rider, M-LOK is a buttstock accessory for rifles that adds a longer, flatter contact surface where the rear of the rifle meets the support bag. On a precision setup, that change has a direct effect on how the rifle behaves shot to shot. Instead of the buttstock pressing into the bag at a shorter or less consistent point, the bag rider gives the rifle a more controlled path during recoil, which helps maintain alignment and reduces unwanted movement.

This version uses an M-LOK attachment interface, making it a practical choice for compatible buttstocks that already use that mounting standard. MDT pairs the design with a 6061-T6 aluminum body and a Mil-Spec Type II hard-black anodized finish, so the accessory remains light enough not to upset rifle balance while still standing up to repeated installation, transport, and range use. The slim shape is designed to match buttstock width, while the rounded front and sides reduce snagging on bags and gear during setup changes.

One of the most useful details is the 5" support length, which gives the rear bag more surface to work against. In practical terms, that can make the rifle easier to settle, easier to steer with subtle pressure, and more consistent when shooting from supported positions. Because the rear does not overhang in a way that interferes with adjustments, it integrates cleanly into a rifle built for deliberate, repeatable shooting.

About MDT

MDT Sporting Goods was established in 2009 and began in Chilliwack, British Columbia, Canada. The company focuses on equipment for target shooting and hunting, with a product range that includes rifle chassis systems, magazines, buttstocks, and accessories. That specialization is directly relevant here, because MDT’s accessories are developed as part of a broader precision-rifle system rather than as isolated add-ons.

MDT says its chassis, magazines, and accessories are developed with input from competitive precision shooters, which helps explain the company’s emphasis on practical ergonomics, repeatability, and compatibility across rifle platforms. Its catalog also includes bipods, scope bases, and scope rings, and MDT identifies the TAC21 as its first chassis. Today, the brand is widely associated with modular rifle components designed to improve stability, fit, and handling for shooters building a more capable precision rifle setup.
