"MAKE SURE YOU HAVE THE RIGHT GUN! i bought i boneyard umarex ump 45 and this part is not compatable. its a bit misleading because the ump's sold on this site dont even use this part sooo.... yeah that doesnt make sense. also there arent enough photos to see the design and internal construction of the piece to confirm compatability. the securing pin under the gearbox is in a totally different place, the rear securing pin slot is designed differently, and the front swing hooks are too small compaired to my umarex/HK body design. Basically, check for brand compatability FIRST.
