B&T MBT Folding/Telescoping Stock Assembly w/Hydraulic Buffer, APC223/APC556/APC300 For Sale

The B&T MBT Folding/Telescoping Stock Assembly w/Hydraulic Buffer APC223/APC556/APC300 is a modular stock system designed for compatible B&T APC-series platforms, including the APC223, APC556, and APC300. It combines folding and telescoping functionality with an integrated hydraulic buffer system designed to improve the stock assembly’s mechanical characteristics.

Stock assemblies are important components of firearm ergonomics, providing shoulder support, adjustability, and improved user interface. A folding/telescoping design allows the stock configuration to be adjusted for storage, transport, and individual fit preferences.

The B&T MBT stock features side-folding function, eight telescoping positions and an adjustable cheek piece. Includes the hydraulic buffer assembly.
Fits the B&T APC223, APC556, APC300

Key Features

The MBT Folding/Telescoping Stock Assembly incorporates several design elements:

• Folding stock mechanism
• Telescoping length adjustment
• Integrated hydraulic buffer system
• Designed for compatible APC-series platforms
• Compact storage configuration
• Adjustable user fit
• Durable construction materials

Folding and Telescoping Design

The assembly combines two adjustment functions:

Folding Function

The folding mechanism allows the stock to pivot alongside the firearm platform, reducing the overall profile when folded.

Telescoping Function

The telescoping mechanism allows adjustment of the stock length, helping accommodate different user preferences and equipment configurations.

Together, these features provide a more adaptable stock system compared with fixed designs.

Hydraulic Buffer System

A defining feature of this stock assembly is the integrated hydraulic buffer.

Hydraulic buffer systems use fluid-based damping technology to manage mechanical movement within the stock assembly. This type of system is designed to provide controlled movement and improve the overall feel of the platform during operation.

The performance characteristics of hydraulic systems depend on the specific firearm platform, ammunition, and configuration.

Compatibility

The MBT Folding/Telescoping Stock Assembly is designed for selected B&T APC platforms, including:

• APC223
• APC556
• APC300

Compatibility may depend on the exact firearm model, generation, and configuration. Manufacturer specifications should be consulted before installation.

Construction and Engineering

B&T stock assemblies are developed with a focus on:

• Structural durability
• Precision manufacturing
• Reliable adjustment mechanisms
• Long-term mechanical performance

The combination of folding hardware, telescoping components, and hydraulic elements reflects a modern approach to firearm stock design.
