This is a 3D printed PLA+ hk416 handguard that I designed and printed, it is a tight friction fit over the original barrel nut that will not come off. The PLA+ makes it incredibly strong and it has been sanded and painted so it has a very smooth finish. It also includes a vertical Foregrip that screws directly into the handguard. Total weight is around 250g so it’s a great replacement for the very heavy rail the gun comes with
