The Company you are looking for is A & W Shot Diverter in Texas. As usual they went out of business. Someone at that time started to make them again but do not know who. I have a 4 - l on an 870 and I am trying to find a 2-1 at the present time. If you get lucky pls let me know. A 4-1 on a short 870 barrel would put 41 #4 buck in a 2ft x 8ft pattern at 25 yards.
