Half finished - Luth-AR MBA-5 Stock Assembly

First off, I have been a fan of Luth for years. This stock started out as a good idea but they forgot to finish it…or it was finished as an after thought. I still can’t figure it out. Super sloppy on the buffer tube. Their is a “clamp screw” on mine to stop the rattle, but it’s nothing like the Picture. You can tighten the screw, but it locks the stock into place and prevents it from being adjustable anymore. Adjustable stock that’s not adjustable is counterintuitive.
