No , all you can do is set it for [like mine 15 ft or so. ] Make sure the bands are new and maybe 1" or so shorter than stock as that will keep it right on the money for 1-18 ft.Shaft drop is rapid after 18 ft, so dont use too long a spear shaft as every once of sttel now drops the shaft on the long shot.

Hi,

Thanks and interesting stuff. Can you tell me if you are able to adjust your point of impact and how much is needed for adjustment. I am especially interested in vertical change as I would like my gun to be sighted in at 6 meters and when I did the match it seems that I would have to elevate the back sight quite a bit to compensate for 6 inch drop. Again thanks for the reply.
