M16 Ultimate 3in1 Hop Up Unit

The Madbull M16 Ultimate 3in1 Hop Up Unit is a metal hop up chamber and can be seen as an upgrade from the original hop up chamber.

This Hop Up Chamber is also equipped with a Chamber Lock which means that when the magazine is removed from the replica, there is no more unnecessary bb's to fall on the ground. There must in this case always be taken into account this fact and when you take the replica in hand you must always treat it as if it were loaded. So always wear your safety glasses and do not point it unnecessarily at someone else.... there can still be bb's in the replica.

Also you can in this Hop Up Unit a LED Tracer Unit install, this is optional.

Furthermore, the unit is equipped with an easy adjustment wheel so you can adjust the hop even better and easier.
