As an indication of how much I like the SAI 6 scope, I acquired another to use with the Wilson Combat upper in 300 Blackout I got to use on the Protector S lower. The second scope has the 7.62 bullet drop reticle and although I’m still not a fan of BDC reticles, I figured it would be a little closer to the calibration necessary for the 300 BLK than my earlier 5.56 sight.

One thing I must mention: Earlier I posted that the 1× setting provides a true no-magnification image, and that’s what I believed to be true after initial use of the original scope. Recently, though, I saw a presentation by a Leupold company representative who discussed the effect of changing the diopter setting for reticle focus. He said that changing the setting can result in a magnified image, and that if a true no-magnification view was necessary, the setting should not be changed.

Because of my deteriorating eyesight I did change the diopter setting to sharpen the reticle, and after seeing the discussion about how that could increase the image magnification I went back and conducted a careful test. The result? Sure enough, at the current diopter setting there is slight magnification of the viewing image at the 1× power setting. Based on the Leupold guy’s comments I believe that will be true of all low power scopes having a 1× magnification setting, but it’s something to be aware of.
