The B&T Side Folding Stock For HK MP5 (UMP Style) brings the proven Swiss-made B&T folding design to full-size MP5 and MP5SD platforms. Built from durable polymer with steel reinforcement, it offers a solid, wobble-free lockup that feels like a fixed stock while still folding flat against the receiver for compact storage and transport. The integrated adapter is designed specifically around HK-spec push-pin mounting, making installation straightforward on compatible MP5-style rifles and carbines.

This stock is ideal for shooters who want to maintain a comfortable cheek weld and full-size ergonomics while gaining the flexibility of a folding configuration for range use, training, or general-purpose duty-style shooting. Its UMP-inspired profile balances light weight with rigidity, and the included sling attachment point supports modern carry methods. B&T’s reputation for precise engineering and OEM-grade quality is evident in the tight fit, smooth hinge action, and refined overall feel of this MP5 folding stock.
