Hop Up Chamber G&G GR14 Series

 This G&G GR14 Series hop up chamber is made entirely from metal. It’s suited for the GR14 Series airsoft replicas by G&G and it serves as a replacement for the standard hop up that the replica comes with. The G&G GR14 Series hop up chamber has a selection wheel towards the rear, which can be used to adjust the hop. Once the hop up unit is installed in the airsoft replica, you can pull back the charging handle to expose it and adjust it.
