Ron, I've shot with disabled guys at three ranges and in each case a movable platform or rest was set up so that the shooter could use any bench on the line, thereby drawing and rotating with the group of shooters In two cases it was wheelchairs and the accommodations was just a short built-up platform, a "stack of plywood" for lack of a better term so his chair came up to ht. The other guy brought his own armrest kinda' thingy. In any case I think it's best if the accommodation work for any bench on the line....
