The Hexmag HX20AR15BLK is a 20-round polymer magazine designed for AR-15 rifles chambered in 5.56x45mm NATO. If you're building a compact rifle setup, training on a budget, or just prefer magazines that don't bulk up your kit when rounds matter less than shootability, this shorter-format mag delivers reliable function without the footprint of a standard 30-rounder. Hexmag has built a reputation for durable polymer magazines that feed consistently, and this 20-round version maintains that track record while giving you a lower-profile option for the range, duty use, or wherever a smaller magazine fits your mission.
The shorty format makes a real difference in how your rifle handles. A lighter, more compact mag isn't just a feel-good thing—it reduces overall gun weight, improves ergonomics when shouldering, and makes prone shooting and barrier work genuinely easier. The black polymer construction resists corrosion and handles rough environments without the maintenance overhead of metal. Whether you're running a precision rifle, an entry-level tactical build, or a trainer gun, a 20-round magazine is a smart complement to your standard mag collection.
Hexmag magazines are known for reliable feeding across a wide range of ammunition types and conditions. The engineering is straightforward and proven: solid polymer body, quality feed lips, and a design that doesn't overthink things. This isn't a niche product—it's a practical, field-tested option from a maker that understands AR shooters.

Yes, the HX20AR15BLK is designed for AR-15 rifles chambered in 5.56x45mm NATO. It fits the standard magazine well and feeds reliably.
A 20-round magazine reduces overall rifle weight and profile, making the gun faster to handle, easier to shoot prone, and more compact for training or duty use. It's also practical when you don't need the full capacity.
Hexmag polymer magazines are built for field use and handle rough handling, environmental exposure, and regular cycling without degradation. Polymer resists corrosion and requires minimal maintenance compared to metal.
