Madbull feeding problem

[B1LLYTHEK1D]

Hi there, I've got an ICS M4, and I recently installed the madbull hopup/and tight bore, but it will not allow bb's to pass through the bucking. Any help please thanks

Oh yah and I'm a newb and I likely installed it wrong, although I've gone over it dozens of times with the instructions and video.

Which rubber? Did you install the bucking so it lays flat in the opening?It needs to lay flat horizontally from left to right of the barrel.

Is the bb getting stuck while firing or when you drop a bb down by hand?

More details will help

if you have put a madbull hop up on an ics m4 you will have to change the noozle cause ics have a shorter nozzzle than other brand
