Hi guys is there anyway I could resolve the issue of bb jamming just inside the hop in a madbull tbb ?? It's a guarded clear hop rubber

What bb's are you using, is the hop up on too much? check down the barrel for any inconsistencies. Take apart and re-asseble hop up and barrel

I'm using green devil bio BB's as thatsall my site allows
Never had trouble in my Masada with the same hop and barrel
And will give that a go and see what happens cheers I was thinking could it be the hop rubber as its brand spanking new and still abit hard ??
