MDT HNT26 Ultralight Hunting Chassis – Remington 700 Long Action CIP 3.850, Folding ARCA, Black Carbon Fiber
The MDT HNT26 Hunting Chassis combines ultralight magnesium construction, premium carbon fiber components, and adjustable precision rifle ergonomics in a purpose-built backcountry hunting platform.
This 106131-BCF configuration is designed for right-handed Remington 700 Long Action rifles using the CIP 3.850-inch magazine system. It features a folding carbon fiber buttstock, enclosed carbon fiber forend with integrated ARCA mounting, and MDT's classic Black Carbon Fiber finish.
For hunters building a lightweight long-action rifle, the HNT26 provides the structural rigidity and versatility of a modern chassis without the unnecessary bulk of traditional aluminum competition systems.
Ultralight Magnesium & Carbon Fiber Construction
MDT developed the HNT26 specifically for hunters who want the benefits of a precision chassis in a lightweight, field-oriented package.
The system combines an AZ61A magnesium alloy chassis core with a carbon fiber forend, carbon fiber pistol grip, and foam-filled carbon fiber buttstock.
The HNT26 family begins at approximately 26 ounces in its lightest configuration. Folding ARCA models weigh approximately 31 ounces, with actual weight depending on the action inlet and configuration.
Carbon fiber contact surfaces also help reduce the cold-metal feel associated with conventional aluminum chassis systems, making the HNT26 comfortable to handle during demanding hunting conditions.
Remington 700 Long Action – CIP 3.850 Magazine Compatibility
The MDT HNT26 106131-BCF is designed for compatible right-handed Remington 700 Long Action rifles and selected Remington 700-pattern custom actions.
This particular configuration uses the 3.850-inch CIP long-action magazine well, designed around compatible extended-length AICS-pattern detachable magazines.
The CIP magazine format is especially relevant to certain long-action magnum cartridges and precision hunting rifles that require a longer magazine configuration.
Important: The 3.850-inch designation identifies the magazine format, not the maximum cartridge overall length. Magazine compatibility depends on the rifle's chambering, receiver dimensions, and magazine design.
This is not the Remington 700 Short Action inlet. Confirm the correct receiver and magazine configuration before ordering.
Folding Carbon Fiber Buttstock
The HNT26 features a folding, foam-filled carbon fiber buttstock that reduces the rifle's overall length for transportation and storage.
The buttstock retains the ergonomic adjustments expected from a premium precision rifle chassis while minimizing unnecessary weight.
- Folding Design: Compact configuration for transportation and storage.
- Foam-Filled Carbon Fiber: Lightweight construction with vibration-dampening characteristics.
- Adjustable Cheek Riser: Helps establish consistent eye alignment behind the optic.
- Adjustable Length of Pull: Approximately 12.5" to 13.5" using the included spacer system.
- Low-Profile Exterior: Smooth contours designed to minimize snagging on clothing and equipment.
Integrated ARCA Carbon Fiber Forend
This HNT26 configuration includes an enclosed carbon fiber forend with an integrated ARCA mounting interface.
The built-in ARCA surface provides convenient compatibility with appropriately equipped tripods, bipods, and other shooting supports without requiring a separate full-length accessory rail.
The forend also incorporates M-LOK accessory mounting provisions, offering additional flexibility for compatible equipment.
With barrel clearance up to approximately 1.25 inches in diameter, the HNT26 accommodates a broad selection of factory and aftermarket hunting barrel profiles.
Integrated V-Block Bedding
At the center of the HNT26 is MDT's precision-engineered magnesium chassis with integrated V-block bedding.
The rigid bedding interface provides consistent receiver support without relying on the flexibility of a conventional factory stock.
Combining this structural foundation with lightweight carbon fiber components makes the HNT26 a compelling choice for premium long-action hunting rifles.
Black Carbon Fiber Factory Finish
The Black Carbon Fiber configuration highlights the HNT26's woven carbon fiber components with a clean, understated black appearance.
The dark finish complements stainless steel, blued, and carbon-wrapped barrel configurations while maintaining a classic hunting rifle aesthetic.
Unlike custom-painted chassis systems, this is a genuine MDT factory configuration that preserves the original carbon fiber construction and finish.
