Reliable, durable - Duramag 6.5 Grendel Stainless Steel 5 Round Rifle Magazine

Have used the 5,10,20 Grendel versions and the 7.62x39 in 5,10,20,28,32 (I believe) versions since 2018. A couple had issues and Duramag replaced them. That would be 2 failures out of about 28 magazines. These get used hunting and on the range, where they get dropped a lot so they are all scratched up. Rest have never been an issue.
Relatively easy opened to clean too. I painted the Grendels to distinguish them, but it scratches off easy.
I still grab a few when they go on sale.
