Description
This is an original Heckler & Koch 40-round steel magazine, purpose-built for the HK33 and HK53 series of rifles chambered in 5.56x45mm NATO. Produced in West Germany, this is a genuine H&K magazine—not a commercial reproduction or aftermarket clone.
Constructed from high-strength blued steel, the 40-round mag was standard issue for infantry and special units using the HK33 and its compact variants throughout the Cold War. It offers reliable feeding, a strong follower spring, and rugged welds designed to survive hard field use. This example remains fully functional, with intact feed lips and only light external wear from honest service use—no dents, rust, or mechanical issues.
Collectors and shooters alike recognize this mag as an essential pairing for factory-correct HK33, HK53, and HK93 builds, whether in semi-auto or NFA configurations. These extended-capacity mags are increasingly difficult to source, especially in complete, operational condition.
Whether you’re restoring a period-correct Cold War rifle setup or stocking dependable spares for your H&K clone, this original 40-rounder delivers authenticity, quality, and performance that modern reproductions can’t match.
