Angel Custom CNC aluminum hop up chamber. Got this to replace the broken hop up on a JG G36C. This is just the hop up chamber with the anti reverse lever, no bucking, nub, or any other parts. Original box. Not even 20 rounds and the adjustment wheel(from different manufacturer) broke. What is being sold here is what was in the original sale from manufacturer. All sales final. Shipping only to lower 48 States. Hop Up payment only, no trades. Please allow time to ship due to work schedule and/or weekends/holidays.
