Well i just got my 70-MM BB GTQ, i took it out of the box took a couple of pics and placed it back in, my son comes in and wants to see it , so i take it out and notice this, it looks like a piece of it is broken
is this damaged? i do not want to have my mechanic install it and have somethimg go wrong need feedback, but i think i will be calling back the vendor in the morning, this sucks i went from one end of the spectrum to the other:frown:
should i worry? could this throw off anything? i have no idea what that white stuff is?
