The AR-1 training target has multiple scoring zones to challenge even the most veteran shooters. The AR-1 target has several impact areas with two unique sighting images to help improve AR shooting skills, and assist in perfecting your shot. The AR-2(CB) training target is printed on heavy-duty card board, creating a more sturdy target.
