Built for Precision and Performance

Crafted by KWA, a brand known for its elite airsoft engineering, this spare gas blowback magazine is tailor-made for the KP45 Compact and USP Compact pistols. It is not compatible with full-size KP45 / USP models. Engineered to integrate perfectly with KWA’s NS2 gas system, this magazine ensures efficient gas usage, crisp blowback action, and consistent FPS delivery.

NS2 System – Enhanced Gas Efficiency

The KWA NS2 System is well-regarded for its exceptional gas efficiency and performance, even in colder environments. By optimizing gas flow and blowback mechanics, this system enhances reliability and consistency with every shot. The spare KP45/USP Compact mag utilizes this system to deliver smooth cycling and solid recoil, giving you a tactical edge when precision matters most.

Magazine Design & BB Compatibility

This KWA gas magazine is built to rigorous standards using durable materials designed to withstand regular field use. Designed to accept 6mm airsoft BBs, it performs best with KSC 5.88mm BBs due to the unique design of the USP series magazine feed chamber. While most high-quality 6mm BBs will function, optimum feeding may require proper BB lubrication and careful stacking to prevent jamming—especially during rapid-fire engagements.

To achieve best results, pair this magazine with high-grade precision BBs, and consider pre-lubing or cycling the spring a few times for smooth feeding during intense gameplay.

Manufacturer Insight: KWA & Umarex

KWA’s craftsmanship speaks for itself, but it’s worth noting that the Umarex / Elite Force brand—which helps distribute KWA products—is also a major player in airgun and airsoft innovation. Since 1972, Umarex has provided top-tier performance gear for sport shooters, law enforcement training, and hobbyists worldwide. Their dedication to realism and quality aligns perfectly with what this spare magazine delivers in terms of function and durability.

⚠️ Warranty Notice: Modifying this gas magazine with aftermarket HPA fittings or valves will void the manufacturer warranty due to the risks involved with high-pressure systems. It’s strongly recommended to use the magazine as intended with green gas for longevity and safe operation.
