Geissele’s hand guard is called Super Moduler Rail (SMR) that used by the US military special forces has also been confirmed. It is also supported by users who use the HK 416 as a civilian specification after changing the elements like the mill spec.
All the parts used in the kit are scraped with high precision CNC and the aluminum material adopted in the receiver and hand guard is T6061, so we use light weight and high strength material. Tokyo Marui MWS gas blowback compatibility with internal parts is very good and you can use it without trouble.
