Have you looked at the Burris Speed Bead with either a Burris Fast Fire or Vortex Venom? I also have a SBE2, and that was my original plan, then I went to Walmart and got a TriStar Raptor 20 gauge. I decided to build that into a turkey gun.
Several years ago decided on a dedicated turkey gun. Decided to have my 12 ga 3.5" Browning Gold Stalker for the gun. Had receiver drilled & tapped & mounted Bushnell Trophy XLT Scope 1.75-4x32mm w/Circle-X Reticle. Gunsmith suggested a Weaver #62 base which has a rock solid 5 screw mount to supplement my Warne solid steel low rings which will handles the heavy 12 ga 3.5" magnums recoil. Love the generous eye relief plus great field of view of this scope!!
If you would like to stay with a bead and be able to see it . Try a champion easy hit long bead. I have 2 of these on Turkey guns. I donít like a scope on my turkey gun. I have the longer one in green. The end of the fiber optic is inside the tube so you have to be down on it to see it. You would have to be blind not to be able to see it well. Killed lots of turkeys with that!
Or go with the Burris FF3. I would do one of those before a scope.
