The HK MP7 Gas Blowback (GBB) is a revolutionary design that replicates the famous personal defense weapon from Heckler & Koch. Our legendary HK MP7 gas blowback SMG set the standard in black, but why should black guns have all the fun? Get the same great MP7 performance in Dark Earth Brown. The HK MP7 Gas Blowback (GBB) is a revolutionary design that replicates the famous personal defense weapon from Heckler & Koch. An interesting fact about the firearm version is that it's chambered in a unique round used almost exclusively by the MP7 and was designed to increase the ability to penetrate high-quality body armor. While the airsoft version certainly cannot penetrate body armor, it does offer a few unique traits of its own among its airsoft gas blowback peers. Ambidextrous fire controls, a satisfying muzzle report, and well-respected KWA gas internal parts are just some of the features that add up to make the HK MP7 GBB airsoft submachine gun the ultimate option for Airsoft close quarter battle players. For heart-stopping fun with serious stopping power, add the HK MP7 Gas Blowback PDW in Dark Earth Brown to your arsenal! Licensed Trademark of Heckler & Koch GmbH
