this look good very crowse. the aim could be a little further , so we can use the free aim to lower the weapon. you could find the limit where you can walk with the gun aimed down in free aim looking straight forward.. and set the distance here..
you might anwser that the hole will be too small, but its still way bigger than the mp5 or G3 sites "hole" .
i like turin idea, but i think the aimpoint is not meant to be used with the eye really close to it, its more like a reflex sight. if you want to really aim with that gun, theire is the scope. plus its not practical to walk around with a limited FOV..
unless you enlarge the HOLE so that ALL the screen green.. but that wouldnt be too realistic
another point why i find this screen good, is that the scope device is close to the eye on the screenie.
the user uses the weapon with the eye close to the scope device (this position) and imho, he uses the aimpoint for reflexes shoots, without getting closer to the aimpoint.
