Ive been looking over scope options, range finders and risers...i think im going to go with a mil dot scope so i can use the mil dots to estimate range based off of known sizes of objects. Anyone have a good mil dot scope to recommend, i think a 3x9 or 4x32 would be good. Im not near my mask right now..anyone know the average height of a paintball mask in inches, im thinking it will be about 9. I know they will vary be manufacturer and model but some mask types and height measurements would help. This will require a little math but is cheaper than a range finder and doesnt require a spotter.
