There are some vertical mechanicals that have shown a tendency to open in flight, largely due to the amount of force released when you squeeze the trigger on a crossbow. I can not say if the Rage is one of them or not. I use the Xbow model Razortips by Grim Reaper, because they (supposedly) have different retention clips than the regular model. I've never had an issue with them, and highly recommend them. I prefer to not to have any worries at the moment of truth.
