Realistic Look and Metal Body:
Specna Arms has masterfully replicated the shapes and ribs of the classic NATO standard magazine (STANAG). Abandoning polymer in favor of a solid metal body, this magazine returns a cold and realistic tactile feeling, perfect for those who love "Mil-Sim" setups and the metallic noise during magazine changes. Thanks to its standardized dimensions, it slides perfectly and smoothly into any M4 magazine pouch on your tactical gear.
Reliable High-Performance Mechanism:
Specna Arms' goal was to create a universal magazine that would feed well not only on its own replicas, but also on those of other brands. The result is an enhanced internal mechanism (Hi-Cap) capable of storing 300 BBs and equipped with an exceptionally strong winding spring. This system guarantees smooth and void-free feeding even on custom replicas with high rates of fire (20+ BBs/s) and effortlessly pushes even heavy ammunition (0.30g and up).
No Speedloader: Being a winding magazine (Hi-Cap), remember never to force the BBs through the exit hole using syringe-type speedloaders! To fill it correctly, open the rectangular window on top of the magazine and pour the BBs in a "rain" directly into the large tank.
Continuous winding: Specna Arms guarantees that, if fully loaded, the spring of this STANAG can theoretically empty almost the entire magazine in one burst. However, the best tactical advice for Hi-Caps is continuous winding: during breaks in combat or while moving from cover to cover, always give a quick "spin" to the wheel on the bottom. This way you will always be sure to have maximum tension and you will not run dry at the most critical moment!
Post-game rest: Metal magazines are very robust, but the internal spring is made of steel and needs rest. At the end of the day, always empty the remaining BBs and turn the wheel to empty the tension completely.
