Well made but definitely 6061 - JE Machine Tech AR15 Receiver Extension No Foam Pistol Buffer Tube

This buffer seems well made and the finish is nice, but I bought it under the impression it was 7075 aluminum (stated multiple times on product page). I received the package, and what's the first thing I read on the label? 6061 aluminum. I haven't installed it, so I can't say whether or not it functions as intended, but based on presumed quality, I'd recommend it. Just be aware, this buffer tube is absolutely NOT 7075.
