Official Umarex / H&K Quality:
When you hold an iconic replica like the Heckler & Koch USP, the experience must be perfect in every detail. This original Umarex CO2 magazine keeps its promises: thanks to its heavy-duty metal construction, it boasts an empty weight of 340 grams. By inserting it into the grip of your USP, you will perfectly balance the weapon's center of gravity, obtaining a tactile feeling entirely comparable to that of the real firearm counterpart.
Power and Resistance on the Field:
CO2 power is the preferred choice for those who do not want to compromise with temperatures. This magazine cancels the Cooldown effect, ensuring that the heavy slide of the USP cycles decisively from start to finish. Furthermore, the hybrid design with a metal body and thick polymer base is designed for action: the metal contains the high gas pressures, while the lower polymer "Bumper" protects the magazine by absorbing shocks in the event of accidental drops or dynamic reloading.
Real Simulation (Low-Cap): Having 18 rounds available forces you to play intelligently. You can't afford to "water" the opponent with blind bursts. This magazine is for realism purists: aim carefully and prepare to reload while taking cover. We recommend having at least a couple of spares in your tactical gear to calmly face a prolonged engagement.
Pay Attention to the Polymer Base: The polymer Bumper is great for protecting the magazine if you drop it on grass or dirt. However, avoid repeatedly smashing it on reinforced concrete or sharp stones: with its 340 grams of weight, the inertia of the fall could damage the plastic in the long run. Always use a Dump Pouch!
CO2 Management: To insert the 12g cartridge, you will need to slide or remove the base depending on the model. Remember the golden rule of CO2: tighten only enough to pierce the capsule and seal the O-Ring. At the end of the game, vent the gas and ALWAYS remove the empty cartridge before putting the magazine back in the holster or backpack.
The H&K® USP CO2 manufactured by Umarex is a faithful...
