Another practicalinnovation from MADBULL. this new metal hop-up unit / chamber has 3 functions in1!
1. LED Tracer Unit(Optional and Included)
2. Chamber Lock(Prevents BBs from falling out when you eject magazine)
3. Easy adjustmentusing new design dial for more stable hop-up
This set alsoincludes a free MADBULL blue 60 degree SHARK hop-up bucking rubber.
Note that thechamber lock function works via an O-ring in the BB feed tube that goes up tothe firing chamber.
The O-ring prevents BB’s from falling out of the gun whenyou pull the magazine out. which is normal in a Marui type gearbox.
If you findthis causes any problems for you. or you prefer that the 3-4 BB’s in the feedtube fall out of the
gun during reloads. you can simply remove this O-ring todisable the chamber lock function.
New hop-upadjustment dial stays in place and won’t shift from vibration during full-autofiring. giving you
more reliable and consistent hop-up than in traditional gunswith slide-type hop-up adjustment lever.
