Actually shot two today. First was my 35e with a "deluxe" Anschutz diopter with anti glare tube that I recently got from Bear-of-Grayling. That sight combo, and I had added a rear anti glare tube 35mm with a Gehmann 510 iris looked rather big so I first tried to switch the Anschutz anti glare tube to another on my HW 77, but it did not accept front tubes, so just swapped sights and re zeroed both. Suprisingly even with changing sights gun to gun they were relatively well zeroed, minute of soda can at about 15 yards, but got the targets out and dialed them in. I got some anti glare tubes from Champions choice so I could move the sight body forward on the dovetail grooves, so the clamping knobs would not be too close to the safety, plus they put the actual iris closer to my eye, increasing sight radius a little. Seems to work fine. Temperature is a little warm, very low 90's today and humidity relatively low for here but it takes me no time wo work up a sweat so shoot a little, go in and cool off then back out.
