Magazine for Umarex CP99 / Nighthawk 4.5 mm

Magazine for Umarex CP99/Nighthawk 4.5 mm is an original replacement for the magazine included with the air rifle.

The 20 BB’s capacity magazine features a durable metal body and a polymer base plate for easier removal from the pistol grip. After inserting the CO₂ capsule, it should be tightened using the bottom screw, which will pierce the capsule and release the gas.

Please note that after installing the capsule in the magazine, it should not be stored inside for longer than 48 hours, as the gas pressure may permanently damage the valve seals. 

The magazine follower can be locked in the lower position, allowing convenient gravity loading of BB’s directly from the package.
