I recently purchased 3 Stainless Steel Duramag AR-15 magazines and they performed flawlessly in my Pre-Ban Colt Car-15. There’s something about using a steel mag as opposed to a polymer type. I use both but these Duramag Steel mags are impressive and I highly recommend them.

Thanks for the great review! We're glad you're enjoying the Duramag magazines - they're definitely a great value!

Duramag AR 15 SS magazine

These magazines are of great quality and will last a lifetime. Great dealing with AT3 tactical..

Thank you for your kind words! We're glad you're enjoying your new Duramag AR-15 SS magazine.

Great Magazines

I've always like the aluminum or steel mags over the polymer mags. To me they are just stronger and look better. The duramag ar-15 stainless steel mag with the orange follower fills that spot. I ordered 5 and will be getting 10 more. I do recommend them.

Thank you for the feedback. We're glad you like the magazines!
