Description
HK Steel Magazine
This HK steel magazine is a factory-style 30-round 5.56x45mm magazine for HK416, MR556, and compatible AR-15 / M16 / M4 STANAG-pattern rifles. It is marked for 5.56mm x 45 and features the heavier-duty stamped steel construction commonly associated with Heckler & Koch military and law-enforcement pattern magazines.
HK Steel Magazine
Unlike standard aluminum AR-pattern magazines, these HK magazines were built with a steel body for added durability and long service life. The magazine has the distinctive curved 30-round profile, reinforced side ribs, steel feed lips, and a dark protective finish.
Construction / Configuration / Pattern
Factory HK-pattern steel magazine in 5.56x45mm. The body is stamped steel with reinforced ribs and a standard AR/STANAG magazine interface. The magazine is marked 5.56mm x 45 with HK-style markings and an AE date-code-style marking.
These magazines are most commonly associated with HK416 rifles, though they are also generally compatible with many AR-15, M16, M4, MR556, and other STANAG-pattern 5.56 rifles.
Historical Context / Development
Heckler & Koch developed the HK416 as a piston-operated improvement on the AR-15/M4 system, and HK steel magazines became a recognizable accessory for that rifle family. Their heavier construction made them popular for hard-use military, police, and collector applications, especially among those wanting correct HK-pattern accessories for HK416 or MR556 builds.
Condition
Very good condition overall. The magazine retains a strong dark finish with light handling marks, minor surface wear, and small rub marks from storage or insertion. Feed lips, body, and floorplate appear intact. A nice example for use, display, or as an accessory for an HK416/MR556 or AR-pattern rifle.
Listing Disclaimer
Magazine compatibility can vary slightly by firearm, lower receiver, and local regulation. Buyer is responsible for ensuring this magazine is legal to own in their location.
