We get to take a look at the Umarex/VFC H&K MP5 A3 GBB Version 2 SMG in this unboxing video by BB2K Airsoft... "A year ago I showed you version 2 of the VFC H&K MP5A3 at Umarex IWA 2021. Today I finally have the most famous submachine gun in the world as a gas blowback on my table. I'll unpack the Heckler & Koch Airsoft with you and do a few test shots."
