Description
Global Ordnance steel magazines are engineered for shooters who want a mag that won't let them down. The 20-round capacity strikes a smart balance between serious ammunition on board and a compact profile that doesn't interfere with bench rest or prone shooting positions. These mags work great if you're running a precision rifle, hunting setup, or keeping your rifle profile low when storage matters.
Constructed from high-strength steel with a rust resistant finish, this magazine handles years of loading, carrying, and shooting without developing feeding issues. The anti-tilt follower keeps rounds stacked consistently from the first shot to the last, eliminating the angled pressure that can cause reliability problems in some designs. Steel resists dents and bending better than aluminum, so drops and hard use won't result in the kind of deformed feed lips that turn a good magazine into scrap metal.
Build Quality and Steel Advantage
You get everything that made the M16 platform reliable for decades. The straight-sided geometry of a 20-round mag means your spring and follower push rounds straight up into your rifle instead of fighting an angle. That also means less spring pressure while loading, so you don't need a loader or a vice grip to top off magazines on a closed bolt. The steel body resists denting from impact, and the rugged dent-resistant construction keeps these magazines functioning even after field abuse.
When 20 Rounds Make Sense
Bench rest shooters and precision competitors reach for 20-round mags because the shorter profile doesn't interfere when shooting from the prone position or from a bench. Hunters also prefer them for the reduced weight and compact size without compromising capacity. If you're building a clone of the original 1964 M16, these fit the bill perfectly. Even for general plinking and training, 20 rounds is plenty between reloads, and you get a magazine that stays reliable for a lifetime of use.

Frequently Asked Questions
Is this 20 round magazine compatible with all AR-15 rifles?
Yes, this Global Ordnance magazine is designed to work with all standard AR-15 platform rifles chambered in 5.56 NATO or .223 Remington. The straight-sided design and standard follower make it universally compatible. You might want to test fit it in your specific rifle to confirm smooth insertion and removal.
What makes steel magazines better for long-term storage?
Steel resists bending and deformation far better than aluminum or polymer, so your magazine will maintain proper feed lip tension indefinitely. You can keep these loaded for years without worrying about the lips spreading or warping. The rust-resistant finish protects the steel from corrosion during extended storage.
Why would I choose a 20-round magazine over a 30-round?
The 20-round capacity offers several practical advantages. It won't interfere with bench rest or prone shooting positions, making it ideal for precision work. The shorter profile keeps your rifle compact for storage, and the lower spring pressure makes loading easier without tools. Many hunters and precision competitors prefer them for these exact reasons.
How do I care for this steel magazine?
Keep it clean and dry to maintain the rust-resistant finish. Never lubricate a magazine or it will cause reliability problems. Avoid dropping it on hard surfaces to prevent damage to the feed lips. For long-term storage, keep it in a dry environment. Replace the magazine immediately if you notice dented feed lips or any deformation.
