Silent Industries Hop-up Bucking Tensioner for ALPHA chamber – Extra tight

CNC Hop-up Chamber ALPHA M4/16 AEG/HPA from Silent Industries is probably the most advanced Hop-up chamber for airsoft guns, offering full support for any hop-up collar length.Revolutionary tensioning system is easily assembled and utilizes retaining rings. You will receive two rings in the package with the chamber – black standard and white looser.
For more precise adjustment, you’ll need to purchase tight and extra tight collar ring. We recommend trying the hop-up rubber ML Super Macaron or Mr.Hop.
