B&T USA NAR Universal Rail Mount MP5/G3 – Optics Platform for HK Pattern Rifles

The B&T NAR Universal Rail Mount provides a rigid mounting platform for optics on HK MP5, G3, and compatible pattern firearms. Designed to replace the factory claw mount interface, this rail system delivers repeatable zero and a lower optical axis compared to traditional claw-mounted optics. The NAR mount clamps directly to the receiver, creating a stable foundation for red dots, magnified optics, or backup iron sights.

Precision-machined from aircraft-grade aluminum with a hardcoat anodized finish for durability. The rail accepts any Picatinny or NATO STANAG 4694-compatible optic mount or accessory. Installation requires removal of the factory claw mount assembly—no permanent modification to the firearm. Mounting hardware and installation instructions included.
