Sorry for the long radio silence, I returned to school and was busy with EE stuff. Now that I’m back at work, I have some time to comment. A rough solution to your problem n4rco would be to add a small invisible hit box to your hud, but this could cause weird problems later (like a player getting snagged by a tree). A better solution would be following the staff members suggestion :).
Also, I found that this form of crosshair was actually bad for use in the oculus rift. By creating a crosshair that floats in front of you, it essentially had the effect of “dirt on glasses.” It was uncomfortable to use, because your eyes will want to focus on the crosshair and the faraway target. In the end I changed my design and made a crosshair that resembled more of a laser pointer.
