Very interested in getting PC9 so thanks for the reviews. Wondering if the zero returns after removing the barrel with the sight mounted not on the barrel.
There's a barrel nut of sorts that regulates the firmness of the barrel/receiver interface. The owners manual indicates zero will be maintained when that ring is properly adjusted.
I have mine adjusted properly, but haven't really tested the return to zero. Now that I have the dedicated optic on board, I will see how that zero holds. Mostly out of curiosity. I will not be breaking mine down all the time, but it is a handy feature when cleaning the bore.
