When I first got my hand on the Umarex Legends MP 40 Blowback CO2 BB Machine Gun at this years SHOT Show I immediately knew it was going to be a hit. The Umarex Legends MP has a lot going for it... High fps, semi and full auto, nostalgia of being a war replica and super great build quality and fit and finish. The questions is really who wouldn't want one? Especially being a replica BB rifle which has to be one of the more limited areas when it comes to airgun replicas. I look forward to shooting this offering from Umarex a little more and sharing my experiences with everyone.
