SB Tactical brace - included RE any good?

I inquired the same thing when I got mine. SB responded to me and said it is extruded 7075 aluminum without any dry lube inside tube. They are just fine.

Mine has been fine. Mortared quite a bit when I first started loading 300 BLK. I had a little learning curve there

Sure, I've seen Chinesium tools fail hilariously, but I feel OK with a made-in-USA 7075 receiver extension from a popular brand like SB Tactical, assuming dimensions and finish check out. No objection if you have a different standard.
