The ECHO 1 MAX Series M4 CNC Hop Up Chamber is a fantastic upgrade over the stock hop up unit in your AEG. It is CNC machined out of one piece of metal which makes it significantly stronger than cast metal upgrade parts. Also, since these parts are sold as a set you can bet that they are made to fit better with each other than any other type of mismatched upgrade part set. An enhanced hop up is a vital aspect in achieving consistent muzzle velocities and consistent groupings.
