Has anyone tried this model:
For barrels, I use a different type, which pins the receiver in a similar fashion, buut it has an extension that fills the internal space, and gives more support when torquing barrels.
This said, it should be remembered that these receivers are aluminum, and it is possible to damage them with these upper receiver blocks. With this in mind, I intend to purchase one of the "reaction rod" types, which appear to me to be the best for stressful applications like torquing/untorquing of barrels.
If you need access to the bore, like for lapping, the Magpul won't work.

While the Magpul unit has a steel support, its mainly polymer plastic.
