This is video review is over an hour for an airsoft pistol, but that's how Reapers Airsoft works, and for this review it's the VFC/Umarex HK P8 A1/USP 2019 GBB... "Hi, today there is the new VFC/Umarex Hecker & Koch P8 A1 and USP GBB (Gas Blowback) for this review/test. Unfortunately a somewhat complex system, which costs time for disassembly and assembly."
