B&T Firearms
The B&T Firearms BT-20155 is a folding stock purpose-built for the HK MP5, combining German engineering principles with modern materials to give your platform a compact, practical upgrade. If you're running an MP5 in a duty, home-defense, or training role where space matters—whether you're working from vehicles, navigating tight quarters, or simply prefer a shorter footprint—a quality folding stock makes a real difference. B&T Firearms has engineered this piece to deliver solid lockup and repeatable positioning without the bulk of a fixed setup.
Built from aluminum and polymer, the BT-20155 keeps weight down while maintaining the durability you need in a workhorse platform. The folding design lets you collapse the stock when you need a shorter overall length, then deploy it for a full cheekweld and control. That flexibility is exactly what makes the MP5 so versatile across applications, and a stock that matches that versatility just makes sense.
Installation is straightforward if you're familiar with MP5 takedown—this is a direct-fit replacement for your existing stock tube setup. Whether you're upgrading a police trade-in, tuning a civilian semi-auto, or building out a dedicated SBR, the BT-20155 gives you the compact-mode option without compromising on stability when you need it extended.

Yes—the BT-20155 is designed as a direct fit for the HK MP5 platform.
A folding stock reduces overall length when collapsed, making the platform easier to store, transport, and handle in confined spaces while still allowing you to deploy a full-length stock when you need proper cheekweld and control.
The BT-20155 combines aluminum and polymer for a balance of weight savings and durability.
