Like I said, only those 3 parts are different.
You may choose to play with the buffers, for example I prefer an H2 buffer in my 6.8, but it runs fine with a standard buffer.
Yup. I ran a standard carbine buffer in one of my 6.8 builds, and the other uses an A2 stock, so a standard rifle buffer works, too.
