How Do I Make R6 View Models?

Hello I Am Working On A FPS Game. I Have Found A Few Tutorials Like

However The First One Has Very Complex Math And OOP Which I Can’t Do A Lot Of.
The Second One Is R15 So It Won’t Be Of Much Help For Me. For The Second One It Has A R6 Place Apparently At The Bottom However The Link Is Broken So It Doesn’t Work.

All I Really Need To Know Is How To Add Sway When You Turn The Camera And Make It So You Can Hold The Gun Via The Motor6D’s The R15 Tutorial Used. And I Was Able To Make Bobbing When You Walk Myself. And Aiming.

So How Can I Make R6 View Model??
