Thread: Does removing action from the stock change zero?

Cleaned up my 'new' Norinco .22 over the weekend. Nice smooth bolt now, and the mag no longer falls out when you look at it.
But I've probably messed up my sighting in haven't I, after taking the action out of the stock and tightening the screws when I put it back in (they were quite loose when I started the exercise).

What kind of POA change should I expect? Will I be starting from scratch?


Identify your target beyond all doubt because you never miss (right?) and I'll be missed.
