The fact that it secures the upper to prevent it from rotating with the torque stresses seems like a good plan. I personally don't see the use of polymers in the construction as a source of concern, since it appears the component with the steel lugs is embedded, and likely adds to the overall stiffness. It's too bad the BCG is employed for longitudinal stabilization, though, as that precludes using a surrogate gas tube to facilitate easier indexing of the barrel nut. At $50, it is quite tempting.
The armorer's tool seems to be solid, as well, but $80 for a wrench seems high to me.
You mean something like this?

An insert would require the reaction rods have something for the insert to work against. A ridge or protrusion on the rod of some sort would need to be machined or welded for that insert to provide additional counter torque.

Quote:Thinking about it, seems like a reaction rod type could have an insert made for the receiver that you'd secure with a pin. Do the same thing, keep the receiver from rotating.
