DuraMag 20rd AR-15 Replacement Magazine - Black with Orange Follower for .223 Rem, 300 Blackout, 5.56 NATO

A DuraMag 20rd AR-15 replacement magazine built for shooters who demand reliability across every condition—from blazing desert stages to frozen backcountry hunts to years sitting in the safe. Where polymer magazines can warp, crack, or lose memory under temperature swings and humidity changes, DuraMag's steel construction holds its shape and function no matter the environment. This is the magazine that works when it matters.

The 20-round capacity makes it ideal for range work, tactical training, and field use where standard 30-round mags aren't practical or desired. The orange anti-tilt AGF follower ensures smooth, reliable feeding while visually confirming rounds as you load—a small detail that prevents the guesswork of a cloudy magazine body. An Everflex spring system keeps tension consistent through thousands of cycles, whether you're cycling ammo at the bench or running drills downrange.

Available in .223 Rem, 300 Blackout, and 5.56 NATO, this magazine pairs with any modern AR platform built for those cartridges. The black finish resists corrosion and blends with most setups. Stock one for each rifle, or grab a few extras for rotation—a solid magazine is the easiest upgrade you can make to your gun's reliability.

Frequently Asked Questions

Will a DuraMag 20rd magazine work in my AR-15?

Yes, if your AR-15 is chambered in .223 Rem, 300 Blackout, or 5.56 NATO. This is a standard AR-15 magazine and will fit any platform built for those cartridges.

Why choose a 20-round magazine over a 30-rounder?

20-round capacity is often preferred at ranges with capacity restrictions, for hunting applications where fewer rounds are desired, and for training drills where magazine changes are part of the workflow. Some shooters also find them more comfortable for prone or bench shooting positions.

How does DuraMag steel construction compare to polymer magazines?

Polymer magazines can degrade under UV exposure, extreme temperature swings, and humidity changes—especially over years of storage. Steel construction in DuraMag magazines resists these environmental stressors and maintains shape and feeding reliability far longer than plastic alternatives.

What's the orange follower and why does it matter?

The orange anti-tilt AGF follower improves feeding reliability by preventing the topmost round from tilting during feeding cycles. The bright orange color also gives you a quick visual indicator of when you're running low on ammunition.
