I was going to do one for AK magazine stamps, but I will leave that for @ZEKESHOOTS.
Most of us have some aluminum or stainless steel AR magazines. To be honest I like the steel and aluminum ones far better that the polymer magazines. The steel and aluminum have more character. They fit into more non- AR 15 firearms as well.
Everyone has a personal favorite and I think that I have a split opinion on my favorite AR magazine. First I love D&H out of Wisconsin.
They use stainless steel and like the D&H mag I have not had a problem with them. The only knock I can give them is that they are a little heavier than the aluminum magazines.
I have run a lot of P-mags and all sorts of other polymer magazines with no problems at all to be fair.
Here are some other good ones to run with.
Here is one with out a stamp!
Here is one that’s now a collectors item.
Palmetto state makes some good ones too. Most are D&H with a different floor plate.
So what magazines do you run and what are your experience with them?
