MDT SRS-X Buttstock Weight

• Rearward Balance Tuning: Adds 0.65 lbs at the back of the rifle system, helping shift the balance point rearward for a steadier hold and a more settled feel on barricades, bags, and prone supports.
• SRS-X Fitment: Built specifically for the MDT SRS-X Elite, SRS-X Lite and SRS-XF Premier buttstocks, so it integrates cleanly into the stock rather than adding bulk outside the rifle.
• Case-Hardened Steel Construction: The steel body provides durable ballast that stands up to repeated installation, transport, and match use where accessories are handled hard.
• M-LOK Clearance Slot: An underside clearance slot allows M-LOK accessories to remain mounted on the buttstock, preserving accessory flexibility while adding weight.
• Simple Hardware Installation: The weight installs in the lower pocket of the buttstock with included screws, making it a practical upgrade for shooters refining rifle balance without changing the rest of the setup.

About the SRS-X Series

The MDT SRS-X series sits in the company’s premium buttstock range for shooters who want a highly adjustable rear stock assembly for precision shooting, competition, and carefully tuned rifle builds. The series is designed around the idea that the buttstock is not just a point of contact, but a major part of how a rifle balances, tracks, and interfaces with support bags and positional props. That is why the SRS-X family emphasizes modularity, accessory compatibility, and a layout that allows shooters to tailor the rear of the rifle to their preferred shooting style.

Across the series, the defining characteristic is its support for balance tuning and rear-end customization. Models in the line are intended for users who may need to adjust weight distribution, cheek weld, and rear support characteristics to suit different barrel profiles, action lengths, and match conditions. The SRS-X platform also supports practical add-ons such as bag-riding and weight systems, which makes it especially relevant for modern competition and long-range rifle setups. In use, the series is built to help the rifle settle more naturally, reduce front-heaviness, and give the shooter more control over how the rifle behaves under recoil and during positional transitions.

About the MDT SRS-X Buttstock Weight

The MDT SRS-X Buttstock Weight is a purpose-built accessory for shooters who need to fine-tune rifle balance rather than simply add mass at random points on the chassis. By placing 0.65 lbs in the lower pocket at the rear of the stock, it moves the balance point backward in a way that can make a front-heavy rifle feel more neutral. That matters on precision rifles with heavy barrels, suppressors, night vision bridges, or other forward-mounted accessories, where excess front weight can make the rifle slower to settle and more tiring to manage through a long stage or range session.

This model is designed specifically for the SRS-X Elite, SRS-X Lite and SRS-XF Premier buttstocks, which gives it a cleaner and more integrated fit than a universal external weight. The case-hardened steel construction provides durable ballast, while the included mounting hardware keeps installation straightforward when adjusting a rifle for a new discipline or a different support setup. MDT also includes an underside clearance slot so M-LOK accessories can still be mounted with the weight installed, which is important for shooters who want to keep their rear-end configuration flexible. In practical use, this accessory is less about adding weight for its own sake and more about improving how the rifle balances on bags, tracks in recoil, and feels from unsupported or improvised positions.
