What is the difference between the Redfield "widefield" and the "Lo-Pro" they look the same to me except for the turret markings. When was each introduced? Is it a mere marketing strategy? or are they different? ....and yes for some weird reason I have an itch to stick one on an AK. My first .22 had one of these on it and the silly TV shape inspires a lot of good squirrel hunting memories and pleasant outdoorsman type vibes.
