thoe the JG416 looks real close to the real HK416, the RIS isnt quite the same.
on the real HK416 as in the VFC416, the RIS has a small tab that inserts into the front notch on the upper reciver which locks the RIS in and stops it from rotating.
good luck with you JG416, you are going to need to find someway of locking it in place.
