It causes the weapon it's applied to to break perspective and missalign far too close to the screen position
The Red Raptor reflex sight is way too close to the shooter's eye, it needs to be moved to the same or at least a similar position as the Markrsman Exakt sight. It should give the same field of view as the Exakt sight so it works as well for rifles and handguns. The Strecker sxs 20 ga uses the exakt sight in the perfect postion and the Cacciatore 12ga pump action uses the Red Raptor with the same eye relief as a magnified scope.
Also, it'd be really nice if the Mangiafico .45/.410 could use a reflex sight of any description
