[Eeyore]

Ok so I've basically put together a WE 416 from parts. I received the final part yesterday which was the barrel and RIS. I took off the rail to attach it to the upper and then re-attached the ris. The RIS wiggles around and when I received it it was did not. Is the only thing holding the rain to the barrel the screw and the quarter circle lugs? Did anyone else have this problem?

Thanks
