Sniper Scopes in TPS

Having a problem involving sniper rifles when playing split screen co-op. It always fires a few inches to the right of where I am aiming.

horizontal or vertical?..or both?

Vertical split. It’s a known issue. The game seems to draw the image for holosight-style scopes and sights from the outside edge of the player’s screen, causing the sight itself to be a little off center (and in opposite directions for each player). Iron sights work normally. When zoomed in, the center of your crosshair should be directly above the middle of your EXP bar.

Once I discovered this, it’s tedious and hard to train your brain to do it, I was able to continue playing normally by adjusting my aiming instinct on such weapons to intentionally offset my aiming.
