The Retro Arms Hop Up Unit is a clean, simple, and elegant entry-level modernization of the classic hop-up unit in a high quality CNC machined aluminum housing
The Hop Up Unit is a small metal device that screws onto the barrel of your airsoft pistol and actually modifies the way it fires by altering the direction of air being sent through it. The result is that your gun will fire farther distances and with greater accuracy than before
The Hop Up Unit works by sending air into the inner workings of your firearm which then makes contact with an internal piston. When you fire your BBs out of this piston, they hit an inner tube inside which then sends that energy back out into your barrel at an increased rate which results in more accuracy for you!
