"Here is a question for you...does anyone know if the anderson lowers are the same hardness as a Colt lower? I kind of regret building a gun using an Anderson lower back during Zero's reign and wonder if it will wear out faster?" from jimmyp.
I suspect it will take a lot of shooting to wear it out.
I have a lower that I built on back about 1976 or '77 that was by Scheutzen Gun Works (that somehow morphed into Olympic or Olympia) and it was machined out of 6061 aluminum that is supposed to be softer than 7075 or whatever they're using nowadays. It's still fine. Doesn't get shot much anymore. The only reason I found out it was the softer alloy is that I had it refinished (re-anodized) and the anodizing processes are a bit different I've been told.
Back when I was taking classes it worked, and a Colt or two I had worked. I never saw any need for anything else. Have them, just don't see that BCM or DD is better than Colt.
Not that it matters but the build might have been a few years later.
