OOP"s was I ever wrong about centre of rail to centre of barrel. I zero/zeroed scope first. Just shooting close but no left or right scope adjustment needed. Looks like there is about 7.5 MOA in the rail .
Loading I just put gun butt down and pushed rounds in with my thumb...
The white box Norinco can be a little difficult to chamber and eject.
So for gun with rail .. Two thumbs up!!!!!
