Apologies, have found the camera thread and asked some more specific questions in there.
Does anyone playing speedball ever use an off axis feed neck so they can sight down the barrel?
It was old school to have the feednecks at a 45 degree angle, then to use a 45 degree adaptor so that the hopper was offset to the side
Watch speedball players and you will notice a way that the cylinder is put in their shoulder and the gun is rotated at an angle. When straight ahead the gun is at 45 degrees
However, let me teach you a trick:
Hold out the palm of your hand in front of your face
Look at it and it obstructs your vision, you will see past it with each eye but it will block what's directly ahead
Bring your hand closer - focus on your hand and it will continue to block your vision
Repeat but as you bring your hand closer keep focusing ahead jus past your hand, as it gets closer your fingers will turn semi transparent
You now have x ray vision
Take a paintball gun with hopper, hold the gun centrally in front of your face, slightly forwards as if you are about to shoot
Hold it so the feedneck is level with your eyes
Focus ahead and the feedneck will turn transparent
Hold it so the barrel is level who your eyes and you will get the sense of looking through the barrel
