I wonder if its really the bb's that shatter the ''loading prong'' of the nozzle?

It might more more the way the back of the part that hold the bbs is designed that is the problem. It is flat and the bolt-muzzle has some play. I modified that part (at an angle) and will test it as soon as i can.

Will still buy one muzzle for testing as well.
