The ProMag HECA9 is a 30-round detachable magazine purpose-built for H&K 93 rifles chambered in .223 Remington or 5.56x45mm NATO. If you own an HK 93, you know how satisfying it is to run a rifle that stands apart from the crowd — and keeping that gun fed with reliable ammunition demands equally dependable magazines. ProMag's Zytel polymer construction delivers the durability you need for range sessions and field use without the premium price tag of steel alternatives.
Built with practical shooters in mind, this magazine features a heat-treated, chrome-silicon wire spring designed to maintain consistent feed pressure through thousands of rounds. The injection-molded follower works in tandem with the spring to ensure smooth, trouble-free feeding whether you're working through rapid drills or steady target practice. The black polymer body resists corrosion and UV damage, so your magazines stay functional in storage and hold up to the wear of active use.
Made in the USA, the HECA9 represents genuine value for HK 93 owners who need spare magazines or want to build out their magazine pool without compromise. Whether you're stocking up for the range or keeping a backup in the truck, this 30-rounder delivers the performance and durability that Zytel polymer is known for.
