I have the Sightron 6 MOA on a Stevens 301 20 ga and a Burris III on a 870. I can dial down the dot to real small for the Sightron and have to make it 1 click larger....can't tell the difference between the Sightron and the Burris. You can make the Sightron brighter and larger dot by turning it up to 6 MOA, which is not necessary for a shotgun in turkey hunting. A well made sight , like it better than the Burris for changing the battery. Great price on a red dot and if I needed another would buy again if that means anything.
