What is the combination used in this video

YouTube - AR-15 rifle with silencer

If not that setup, is there another one that is a good deal?

He said it in the beginning of the video:
Advanced Armament Corporation - M4-1000

I think AAC is a pretty good can and it would serve you well if you went with it.
