Magpul UCS (Universal Carbine Stock) To AR15 5.56 Lower Receiver: How do I do this?

How do I get a UCS to fit onto a AR15 Lower? I have a Noveske Gen 4 Lower. Don’t I still need a buffer tube to fire 5.56?

What are the parts needed - seeking the best premium parts.

Thank You!!!

EDIT:

Answered my own question.

Must be a bufferless system.

Noveske does not have this.

The short answer is that the “universal” carbine stock isn’t universal.

Kinda like USB until the Type C plug.
