The B&T MP5/SP5 Handguard, Tri-Rail is a premium upgrade designed for MP5-pattern firearms, including the HK MP5, HK SP5, and compatible clones. Manufactured by B&T AG, this handguard provides a durable and versatile platform for mounting accessories while maintaining the classic MP5 profile.

Built from high-strength aluminum with a hardcoat finish, the B&T Tri-Rail Handguard replaces the standard MP5 forearm and adds three Picatinny/NATO accessory rails — one on each side and one underneath. This allows users to mount compatible accessories such as weapon lights, lasers, vertical grips, and other rail-mounted equipment.

Why Choose the B&T Tri-Rail Handguard?

The factory MP5/SP5 handguard offers a classic appearance but limited accessory mounting options. The B&T Tri-Rail upgrade adds modern functionality without significantly changing the firearm’s overall appearance. Its rigid aluminum construction provides a secure platform for accessories while keeping the compact MP5 design intact.

Whether upgrading an HK SP5 pistol, a classic MP5 build, or a compatible clone, the B&T Tri-Rail Handguard offers a professional-grade solution for users who need additional accessory compatibility.
