After months, no a couple of years, I broke down and purchased the Burris Speed Bead from Optics Planet for my SBEII. Installation was no sweat, had a little trouble tuning the red dot to slightly above my factory bead. Took the mountings back off, disassembled, back together, then it worked just fine. Powered it up - very cool. I was stoked to get it in the field on a upland game hunt. The next weekend got into the quail, they were just to fast for me to find with the Speed Bead. I work to hard for my birds, to leave it on for the balance of the season. Not a bad deal, leave the mount on, take the red dot sight off with two screws. I did shoot a coyote and a oppossom on that hunt, dead on with the Speed Bead. It should work great turkey hunting and shotgunning yotes. It is going to take some time, for me, shooting clay to say if it is going to work wing shooting, I know it can be done - a local guide has quite a few customers using these and taking upland game. I am hoping to become accustom to it and leave it on the SBEII full time. I also would mount one on a home defence shotgun in an instant, would work great. If you did not have time to turn it on, you can still use the factory bead thru the sight glass. It is very sturdy and I have no fears about damage in the field. Just need to spend the time to train to wing shoot with it, not a point and shoot situation to me yet.
