Complete hop-up unit for V3 AEG's. The main body is machined from high quality aluminium. The hop arm has a fixed plastic nub so if you wanted to use something like a Maple Leaf nub you will need to sand down.
PLEASE NOTE:Not every hop chamber works for every AEG, due to these being made from aluminium they can scratch when fitted. I can only accept returns on hop chambers that are still "as new". Please be sure to do you your own research before purchasing. If in doubt stick to using the original hop chamber.
