Metal Snobbery

It's not really a huge statement to say that all of your magazines are made from steel.

Virtually all magazines are.

Even Glock, which is a steel liner encased in plastic.  There's a company making larger capacity Glock magazines by ditching that encasement and just making a steel body that's just a bit wider.

There's darn few steel AR magazines.

Chris Bartocci went through what was available a couple of years ago.

Part 1:

Part 2:

Most non-plastic AR magazines are aluminum.

I'm not really that impressed with H&K's magazine.  It's heavy and doesn't really work any better than the USGI or PMAG.

And that's what I care about.

Does it work?

The Amend-2 doesn't appear to work.  But the Hexmag, Lancer and PMAG do; despite being plastic.

I'm someone who remembers Orlite and Thermold.  Those weren't good at all.  They also cemented the idea that plastic AR magazines were junk.

Interestingly, the OG Thermold isn't that bad, Canada's attempt to sharpen their pencil on manufacture led to a magazine that didn't last.

It's not the "plastic" per se.  It's what kind of plastic and the design of the magazine that matters.
