Airsoft Chay has recently done a quick review of the licensed HK MP7A1 V2 Gas Blowback SMG, a new upgrade of the VFC/Umarex MP7 series GBB SMG, which was released in 2018. This model is a faithful reproduction of the original, complete with full markings. Notable improvements include the replacement of the plastic outer barrel with a steel one, and the addition of an MP7 type M12-1mm muzzle break.
