My BAR10 with the TDC hop adjuster and shimmed chamber is curving right. This is kinda strange, since the TDC mod should be fixing all problems with curving. This problem is recent, the rifle used to shooting perfectly, and I don't remember anything I could have done to cause the problem.
The weird thing is, I can see that the bucking nub (the part that contacts the BB) is very even/symmetrical when pressure is applied to the hopup arm with the TDC adjuster screw. The fangs on the hopup arm are also even and symmetrical. Also, my barrel looks pristine and I have cleaned it already.
I also suspected the bucking, but it did not look torn at all when I inspected it. I've already tried washing the bucking in soap + warm water. This problem is really stumping me, any ideas?
