I have just bought a Hawk Night eye illuminated dot scope 2.5 –10 X 50. It does everything I need to do but it doesn’t have any parallax adjustment. This means that it comes out of focus quite a bit. I was just wondering if any one knew.

1) what the factory sets the parallax on these scopes.
2) Can the parallax be adjusted say to 35 yards
3) If so, how do you do it.
