Accu-Shot, other than turning it 180 degrees. I feel it can be a useful tool if used properly, and have shot a 5 round 100 yard group measuring .3-inch prone off the bipod with my TRG-22, 175 grain Black Hills Match ammunition, and a Nikon 2.5-10x44mm Tactical scope.
The Accu Shot is fantastic. No reason for anyone to build sand bags.
