So having recently taken the role of a sniper I found one concern with my experience; I have a hard time keeping count of my ammo. So I searched online to find a solution which are either out of my present price range or out of my circuitry capabilities. I found someone had used a calculator with a momentary switch wired to the "=" button so that is exactly what I did. So now every shot I take is displayed on the screen. I plan to just keep the calculator up in my eyesight with a large length of wire until I can afford another way to go at it.
I noticed my problems and like I stated there is a bullet counter out there meant for Halo props that does count but it's $32 plus shipping and that I cannot afford at the moment. The switch was $4 and the calculator was $1 and the wires I had lying around. I have taped the wires up and put the calc between the scope and the rails and it works well like this. This is temporary until I can afford the prop counter
