One 30 round HK UMP GBB mag is cool. But five 30-round mags is a party! The downside to the HK UMP Gas Blowback SMG being so fun to shoot is that the rounds in your 30-round magazine go quick. Better grab a few extra mags to stay in the game until you're the last one standing! Licensed Trademark of Heckler & Koch GmbH.
