6mmProShop CO2 Magazine for Umarex / KWA MP7 GBB Airsoft SMG – 38rd Capacity

Power up your MP7 with unmatched reliability and performance using the 6mmProShop CO2 Magazine for Umarex and KWA MP7 gas blowback SMGs. Designed for players who demand durability, consistency, and aggressive feeding under high-pressure conditions, this heavy-duty 38-round CO2 magazine is the ultimate upgrade for your compact SMG setup.

Whether you're running tight CQB games or extended outdoor skirmishes, the 6mmProShop CO2 mag keeps you locked, loaded, and ready to dominate.

Rugged Construction Built for Combat

The full metal alloy body gives the magazine a realistic weight and unmatched durability in the field. Whether you're diving, reloading on the move, or just running hard, this mag is engineered to take abuse and keep feeding.

A reinforced feed lip and heavy-duty internal components ensure longevity and reduce the risk of mid-game failures. Coupled with a high-tension spring, you'll get smooth, consistent BB feeding even in high-rate-of-fire scenarios.

CO2 Powered for Consistency and Cold-Weather Advantage

Unlike green gas mags that may struggle in cold weather or rapid-fire use, this mag is powered by CO2 cartridges. That means better gas efficiency, harder kick, and more consistent FPS across every shot—even in lower temperatures.

CO2 also allows for snappier bolt action and faster cycle rate, which can give you a decisive edge during high-stress engagements or competition play.

⚠️ Note: Modifying this magazine for HPA fittings will void your warranty. CO2 systems operate at specific pressures that are incompatible with HPA modifications.

Optimized for the KWA MP7 Platform

This magazine is fully compatible with KWA MP7 GBB series rifles and select Umarex MP7 models. Whether you're training, milsimming, or playing competitive airsoft, it locks in perfectly, feeds reliably, and blends seamlessly with your loadout.

With a 38-round capacity, it strikes the perfect balance between compact size and extended firepower—ideal for tight indoor engagements or fast-paced outdoor games.
